An object at rest stays at rest, and an object in motion stays in motion unless acted upon by a net external force.

Front

What is friction?

Back

A force that opposes the motion of an object, causing it to slow down or stop.

Front

What are balanced forces?

Back

Forces that are equal in size and opposite in direction, resulting in no change in motion.

Front

What are unbalanced forces?

Back

Forces that are not equal and opposite, resulting in a change in motion.

Front

What is the effect of a strong force applied in the opposite direction of motion?

Back

It can change the direction of the object and cause it to continue moving.

Front

What is the relationship between force and motion?

Back

Force causes changes in the motion of an object.

Front

What is the formula for calculating force?

Back

Force = mass x acceleration (F = ma).
