Question

1. in which direction do you apply force to either the red ball or the ping pong ball to change its direction?

in the same direction it is going
in the opposite direction it is going
from the side

1. which of newtons laws is also know as the law of inertia?

newtons first law of motion
newtons second law of motion
newtons third law of motion
law of conservation of energy

Explanation:

Question 7

To change the direction of a moving object (like a ball), applying force from the side (perpendicular to its current motion) will alter its path. Applying force in the same direction would speed it up, and opposite would slow/stop it, not change direction.

Newton’s first law of motion states that an object at rest stays at rest, and an object in motion stays in motion with constant velocity unless acted upon by a net external force. This is known as the Law of Inertia. The second law is about force, mass, and acceleration ($F = ma$), the third is action - reaction, and the law of conservation of energy is a different principle.

Answer:

C. From the side
