What is displacement?

Back

Displacement is the shortest distance from the initial to the final position of an object.

Front

What are balanced forces?

Back

Balanced forces are equal in size and opposite in direction, resulting in no change in motion.

What are unbalanced forces?

Back

Unbalanced forces are not equal and can cause an object to accelerate or change direction.

Front

How does changing the height of a ramp affect the distance a toy car rolls?

Back

Increasing the height of the ramp generally increases the distance the toy car rolls due to greater potential energy.

Front

How does changing the surface of a ramp affect the distance a toy car rolls?

Back

Different surfaces create different amounts of friction, affecting how far the toy car rolls.
