I would suggest him to use curved lines to articulate the energy and movement motion n his drawing
Arcs of lines may be referred to as curves segments, rays, or lines depending on how they are linked.
A typical illustration of a curve is the arc of a circle, often known as a circular arc. The term "great arc in a sphere" refers to an arc of a great circle or a great ellipse or a spheroid.The numerous types of curves include simple curves, closed curves, simple closed curves, transcendental curves, and algebraic curves.
A curved line that encircles a central point is what is referred to be a circle. The line is continuously and uniformly curved. If a circle can be folded into two identical pieces, it is considered to be symmetrical.
Thus curved lines can be used to best articulate the feeling.

A car roll down the hill, accelerating at 2m/^2. How far doe it roll in 1. 5 econd ?
So the car rolls a distance of 2.25 meters in 1.5 seconds.
To find the distance the car rolls in 1.5 seconds, we need to use the equation:
Distance = Initial velocity x Time + (1/2) x Acceleration x (Time^2)
Since the initial velocity of the car is 0 (it's rolling down the hill and not moving initially), we can simplify the equation to:
Distance = (1/2) x Acceleration x (Time^2)
Plugging in the values we have:
Distance = (1/2) x 2m/s^2 x (1.5s)^2
Distance = (1/2) x 2 x 1.5^2
Distance = (1/2) x 2 x 2.25
Distance = 2.25m
So the car rolls a distance of 2.25 meters in 1.5 seconds.

Radiation is spontaneously emitted from hydrogen-3 nuclei, but radiation is not spontaneously emitted from hydrogen-1 nuclei or hydrogen-2 nuclei. Which hydrogen nuclei are stable?.
Nuclei of H1 and nuclei of H2 are the only stable nuclei oh hydrogen.
Hydrogen is the first and most basic of all elements in the universe.
It is also the lightest element in the periodic table and 90% of all atoms in the universe are hydrogen atoms.It is represented by the symbol 'H'Radiation is spontaneously emitted from nuclei of H3 because this isotope of hydrogen is highly radioactive as compared to other isotopes of hydrogen namely; nuclei of H1 and nuclei of H2.
The nucleus of H3 also called as tritium contains one proton and two neutrons, while the nucleus of the common isotope H-1 (protium) contains one proton and zero neutrons, and the nucleus of H-2 (deuterium) contains one proton and one neutron.

A bowling ball is dropped off of the side of a building. Ignore the effects of air resistance. As the ball continues to fall freely, the kinetic energy of the ball.
The ball continues to fall, its kinetic energy will increase.
What is kinetic energy?Kinetic energy is the energy an object possesses due to its motion. It is the energy associated with an object’s speed and mass, and is the energy that an object has because of its movement. Kinetic energy can be converted into other forms of energy, such as heat, light, or sound. It can also be used to do work, such as moving objects or powering machines. Kinetic energy is a form of mechanical energy, which is energy that is associated with the motion or position of an object. Kinetic energy is related to the work done on an object, and it increases as the object’s speed increases. Kinetic energy can be calculated using the formula KE = ½mv2, where m is the mass of the object and v is the velocity of the object.
The kinetic energy of the ball will increase as it falls, because it is gaining speed due to gravity.
As it falls, it accelerates at a rate of 9.8 m/s^2, and its kinetic energy is equal to its mass multiplied by the square of its velocity.
Therefore, as the ball continues to fall, its kinetic energy will increase.

Calculate the gravitational force between two people, 60 kg and 70 kg, respectively,
separated by 2.5 meters.
According to the question The Answer is F = 7.008 x 10^-8 N. Because every item in the cosmos that has mass pulls on every other object with a gravitational force, there is a gravitational force.
How to Calculate the gravitational force between two peopleThe gravitational force, which is what pushes mass-containing objects toward one another. We frequently consider the pull of gravity from the Earth. Your body is kept on the ground by this force. However, all mass-bearing objects are pulled toward one another by gravity
The Newton's Law of Universal Gravitation According to Isaac Newton, the gravitational pull between any two objects is inversely proportional to the square of their separation (r) and is directly related to their respective masses (m 1 and m 2). The formula is
F g = G m 1 m 2/ r 2.
G is the universal gravitational constant in this equation.
G = 6.67 × 10 − 11 N ⋅ m 2 / k g 2 .
This is based on the assumption that two people are "standing" 2 meters apart in outer space, free from any other substantial gravitational forces.
F = Gm1m2/r^2
where r is the distance between the centers of mass.
G = 6.6743 × 10^-11 m^3•kg^-1•s^-2 (N•m^2•kg^-2)
m1 = 60 kg
m2 = 70 kg
r = 2 m
F = 6.6743 x 10^-11 N•m^2 kg^-2•(60•70) kg^2/ (2 m)^2

Answer:
Range formula:
R = V^2 sin 2θ / g
sin 2θ = R g / V^2 = 80 m * 9.80 m/s^2 / (30 m/s)^2 = .871
2θ = 60.6 deg
θ = 30.3 deg
Check: 30 * cos 30.3 = 25.9 m/s horizontal speed
t = 80 m / 25.9 m/s = 3.08 sec to reach target
H = Vy0 t - 1/2 g t^2
Vy0 = 30 * sin 30.3 = 15.1 m/s initial vertical speed
H = 15.1 * 3.08 - 4.9 * 3.08^2 = 46.5 - 46.5 = 0

R3= 12.00 Ohms
Solve for all the necessary parts of the circuit to answer the following question:
What is the voltage drop at (V₁) which is the voltage drop at resistor one?
Answer:
To solve for the voltage drop at V₁, we can use Ohm's law, which states that the voltage drop across a resistor (V) is equal to the current (I) flowing through it multiplied by the resistance (R) of the resistor.
V = I * R
The information given in the question is as follows:
VT = 101.00 V
T = Unknown
R₁ = Unknown
V₁= Unknown
I₁=Unknown
R₂= Unknown
V₂= 33.00 V
I₂ = 12.00 Amperes
R₂ = Unknown
V₃ = 37.00 V
I₃ = 13.00 Amperes
R₃ = 12.00 Ohms
The first step is to calculate the current flowing through the circuit by using the formula Power= Voltage * Current
P = VT
I = P/VT = 101/101 = 1 Amperes
Now we can use Ohm's Law to find the voltage drop across R1:
V₁ = I * R₁ = 1 * R₁
To find the resistance of R1, we can use the formula:
T = V₁ + V₂ + V₃
R₁ = (T - V₂ - V₃) / I
Substituting the values,
101 = V₁ + 33 + 37
V₁ = (101 - 33 - 37) = 31 Volts
So, the voltage drop at V₁, which is the voltage drop at resistor one, is 31 Volts.

Answer: 12,100 Joules of Kinetic Energy
Explanation:
Kinetic energy is a measure of how much energy something has because it's moving. To calculate the kinetic energy of a bike, you need to know how heavy it is and how fast it's going. We use a formula that looks like this:
(1/2) x the weight of the bike (in kilograms) x the speed of the bike (in meters per second) x the speed of the bike (in meters per second)
So if we have a bike that weighs 25 kilograms and is going 22 meters per second, we can plug those numbers into the formula like this:
(1/2) x 25 x 22 x 22
And we find out that the bike has 12,100 Joules of kinetic energy.

This means that the ball does not have any velocity when it is at the spring's equilibrium position.
What is equilibrium?Equilibrium is a state of balance where opposing forces or influences are equal and balanced. It is a situation where there is no tendency for change in a system. Equilibrium can be reached in a variety of situations in economics, physics, chemistry, biology, and other fields. In economics, equilibrium is the state at which the market prices of goods and services are stable and consistent with the amount of goods and services that are being supplied and demanded. In physics, equilibrium is a state where all forces acting on an object are balanced and no net force is present. In chemistry, equilibrium is a state where the rates of the forward and reverse reactions of a chemical reaction are equal. In biology, equilibrium is a situation where the forces of natural selection are balanced and no net change in the genetic composition of a population is observed.
The muzzle velocity of the ball can be calculated using the equation v = √2gy,
Where v is the velocity of the ball, g is the acceleration due to gravity, and y is the height of the spring's equilibrium position.
In this case, the muzzle velocity of the ball is equal to √2g*0, or 0 m/s, since the spring's equilibrium position is at y=0.
This means that the ball does not have any velocity when it is at the spring's equilibrium position.
