______ forces affect the motion of an object by speeding it up, slowing it down, or changing the direction of it.

• Balanced
• Strong
• Unbalanced
• WeaK

Which law of motion states that an object in motion will stay in motion and an object at rest will stay at rest unless acted upon by an unbalanced force?

• Newton's 1st Law of Motion
• Newton's 2nd Law of Motion
• Newton's 3rd Law of Motion

An object's resistance to its change in motion is its

• Friction
• Inertia
• Gravity
• Pressure

Which law of motion is explained by the equation:
Force = Mass x Acceleration

• Newton's 1st Law of Motion
• Newton's 2nd Law of Motion
• Newton's 3rd Law of Motion

As the force applied to an object increases, its acceleration______

• decreases
• increases
• stays the same
• does not exist

Is the object in equillibrium?

• Yes

• No

• Not enough information

Projectile motion is produced by ...

• the force of gravity downward
• the horizontal velocity foward
• the horizontal velocity forward and the force of gravity downward
• the forward vertical velocity parallel to the ground

The amount of matter in an object is the 

• momentum
• acceleration
• mass
• weight

If you go to the moon ...

• your mass changes, but not your weight
• your weight changes, but not your mass
• both your mass and weight change
• both your weight and mass stay the same

What factors affect the amount of friction between two objects?

• the type of surface and the velocity of the objects
• the velocity and the mass of the objects
• the type of surface and the force between the objects
• the mass and the distance between the two objects
