TRUE or FALSE:

A falling skydiver which has reached terminal velocity is considered to be in a state of free fall.

• TRUE

• FALSE

TRUE or FALSE:

A ball is thrown upwards and is rising towards its peak. As it rises upwards, it is NOT considered to be in a state of free fall.

• TRUE

• FALSE

TRUE or FALSE:

An object in free fall experiences an acceleration which is independent of the mass of the object.

• TRUE

• FALSE

NGSS.HS-PS2-1

TRUE or FALSE:

A ball is thrown upwards, rises to its peak and eventually falls back to the original height. As the ball rises, its acceleration is upwards; as it falls, its acceleration is downwards.

• TRUE

• FALSE

NGSS.HS-PS2-1

TRUE or FALSE:

A ball is thrown upwards, rises to its peak and eventually falls back to the original height. The speed at which it is launched equals the speed at which it lands. (Assume negligible air resistance.)

• TRUE

• FALSE

TRUE or FALSE:

A very massive object will free fall at the same rate of acceleration as a less massive object.

• TRUE

• FALSE
