Front

What does it mean for an object to have greater mass?

Back

An object with greater mass is heavier and requires more force to move or stop.

Front

How does surface type affect motion?

Back

Different surfaces create different amounts of friction, affecting how easily an object can move.

Front

What is the relationship between force and motion?

Back

Force is needed to change the motion of an object; more force results in greater acceleration.

Front

What is a magnet?

Back

A magnet is an object that produces a magnetic field, attracting certain metals like iron.

Front

What is the purpose of a parachute?
