Newton’s first law states that if a body is at rest or moving at a constant speed in a straight line, it will remain at rest or keep moving in a straight line at constant speed unless it is acted upon by a force.
Newton’s second law is a quantitative description of the changes that a force can produce on the motion of a body. It states that the time rate of change of the momentum of a body is equal in both magnitude and direction to the force imposed on it.
Newton’s third law states that when two bodies interact, they apply forces to one another that are equal in magnitude and opposite in direction. The third law is also known as the law of action and reaction. This law is important in analyzing problems of static equilibrium, where all forces are balanced, but it also applies to bodies in uniform or accelerated motion.

The first law represented in the game would be the candy. If you blow it, it would move but then stop due to friction.
The second law would be represented by blowing the candy. Since the candy was light, it would be easier to blow but if it was heavier, it would be a lot harder.
The final law represented in the game would be if you decided to blow the candy with a ballon instead, the candy would move the opposite direction the ballon is moving.

The net torque on the seesaw is 294 Nm.
<h3>What is torque?</h3>
Torque is the force that tends to rotate the body to which it was applied.
To calculate the net torque, we use the formula below
Formula:
- τ = mgd-m'gd'........... Equation 1
Where:
- m = Jenny's mass
- m' = Tom's mass
- d = Jenny's distance from the pivot
- d' = Tom's distance from the pivot
- g = acceleration due to gravity
From the question,
Given:
- m = 40 kg
- m' = 30 kg
- d = 1.5 m
- d' = 1 m
- g = 9.8 m/s²
Substitute these values into equation 1
- τ = (40×1.5×9.8)-(30×1×9.8)
- τ = 588-294
- τ = 294 Nm
Hence, The net torque on the seesaw is 294 Nm.

The force per unit of length between two wires carrying current is
where I1 and I2 are the currents in the two wires, while r is the distance between them.
We can see from the formula that the force is proportional to the product between I1 and I2:
so, if we double both I1 and I2, we get a factor 4:
so, the force between the wires will be 4 times the original value.
