Newton's Laws

The upward force acting on your parachute as it fell through the air is _________.

• air force
• weight
• air resistance
• upheaval

If you travel to Mars, where gravity is less than Earth's gravity, what will happen to your mass and weight?

• Your mass and weight will both be greater than on Earth.
• Your mass and weight will both be less than on Earth.
• Your mass will be the same, but your weight will be less than on Earth.
• Your mass will be less than on Earth, but your weight will be the same.

What kind(s) of objects have inertia?

• all objects with mass
• only objects at rest
• only objects in motion
• only objects whose motion is being changed

After a cannonball is fired into frictionless space, the amount of force needed to keep it going equals

• twice the force with which it was fired
• the same amount of force with which it was fired
• 1/2 the force with which it was fired
• zero, since no force is requires to keep it moving.
