Force and Motion Unit Exam

Gravity depends the _____________ and _____________ between masses.

• matter/distance

• mass/force

• mass/distance

• matter/force

• and

The greater the object mass, the stronger the gravitational force on it. *

• True

• False

Projectile Motion follows the curved path of

• North and South

• Left and Right

• Horizontal and Vertical

• Up and Down

Occurs when an object has a change in position.

• Speed

• Distance

• Motion

• Velocity

• Acceleration

How far an object has traveled, from point A to point B. There is no direction.

• Speed

• Distance

• Motion

• Velocity

• Acceleration

Occurs when an object changes speed and its direction or both. *

• Speed

• Distance

• Motion

• Velocity

• Acceleration

To find this you must divide distance by time (d/t)

• Speed

• Distance

• Motion

• Velocity

• Acceleration

What is the difference between positive and negative acceleration? *

• Positive decreases in speed, Negative increases in speed

• Positive increases in speed, Negative decreases in speed.

• There is no difference

• Positive increase in velocity, Negative decreases in velocity.

Force is: *

• The total amount of force acting on an object.

• The push or pull applied to an object.

Friction is: *

• A larger mass causing a larger acceleration.

• Always at rest.

• The force that opposes the sliding motion of

  two touching surfaces.
