Gravitational acceleration and free fall PBD test

What would you be measuring if you had the object's speed and direction

• momentum

• velocity

• force

• weight

The picture of the position vs. time graph shows an object that is...

• accelerating/speeding up
• moving at a constant speed 
• not moving 
• accelerating/slowing down. 

What is the standard unit force is measured in?

• Newtons
• pounds
• grams
• meters

If a ball is thrown up and lands at the same location, what was its acceleration?

• -10 m/s² on the way up and +10 m/s² on the way down.

• -10 m/s² the entire time.

• +10 m/s² on the way up and -10 m/s² on the way down.

Free fall is

• moving through the air under the influence of the force of gravity only.

• not paying for a fall.

• clothing sale with lots of orange & brown clothes.

• a feather dropped from an airplane.

A textbook is dropped from a second floor window and falls to the ground. What happens to the acceleration as the book falls to the ground

• the acceleration increases

• the acceleration decreases

• the acceleration remains constant

The state that exists when the only force acting on an object is gravity is called

• free fall

• inertia

• acceleration

• momentum

Heavier objects free fall faster than lighter objects.(in the absence of the air resistance)

• True

• False
