Projectile Motion part 2

What is the definition of projectile motion?

• Motion in a straight line

• Motion in a circular path

• Motion of an object thrown into the air subject to only the acceleration of gravity

• Motion of an object in water.

What happens to the vertical component of a projectile's velocity as it rises?

• Increases

• Decreases

• Remains constant

• Becomes zero

What causes the curved path in projectile motion?

• Wind resistance

• Gravity

• Friction

• Magnetism

In projectile motion, what happens to the object after it goes up?

• It stays in the air

• It comes back down

• It disappears

• It moves in a straight line

In projectile motion, what happens to a ball after it is thrown?

• It stays in the air

• It falls back down

• It moves in a straight line

• It disappears.

Which term describes the path of a projectile?

• A) Launch Angle

• B) Trajectory

• C) Gravity

• D) Speed

Which of the following best describes 'Trajectory'?

• The speed of an object

• The curved path an object follows

• The weight of an object

• The color of an object.

What is 'gravity'?

• The force that attracts a body toward the center of the earth

• The force that repels objects from the earth

• The force that keeps objects stationary

• The force that causes objects to float.

The curved path an object takes after it is given an initial forward velocity is called: 

• terminal velocity
• projectile motion
• sliding friction
