Force creates or changes motion; friction opposes motion.
📌 Linear motion normally describes motion along a straight path, whereas translational motion applies to both straight and curved paths.
1. What is a force?
2. Which statement best defines motion?
3. What role does friction play when two surfaces are in contact?
What is force in physics?
A push or pull that can make an object move, stop, or change direction.
What does motion refer to?
The movement of an object from one place to another.
What does friction do to motion?
It opposes or resists the motion of two surfaces in contact.
What two concepts are involved in walking and running?
Motion and friction between the feet and the ground.
What is translational motion?
Motion where all points on a body move in the same linear direction with the same velocity.
In translational motion, how do all points on the body move at a given instant?
They travel the same displacement, in the same direction, with the same velocity and acceleration.
