If the mass of an object is tripled, what happens to its weight?

• Weight remains the same.

• Weight is doubled.

• Weight is tripled

• Weight is one third the mass.

If the mass of an object is tripled, what happens to its acceleration if the force on the object remains the same?

• Acceleration remains the same.

• Acceleration is doubled.

• Acceleration is tripled.

• Acceleration is one third of what it was before.

What is meant by free fall?

If a heavy object and a light object are in free fall, will one fall faster than the other?

• Yes

• No

If a large object and a smaller object with the same mass are dropped off of the school, which will experience the most air drag? Think about how speed and surface area are related to air drag.

• The large object.

• The small object.

What is the acceleration of any object at terminal velocity?

• The acceleration is 10 kilograms.

• The acceleration is 1 Newton.

• There is no acceleration. The air drag and gravity cancel each other out. Terminal Velocity means the speed is in Dynamic Equilibrium.

• The acceleration is 10 m/s².
