Laws of Motion Unit PRACTICE Test

What is Newton's First Law known as? The Law of

• Friction
• Mass
• Inertia
• Gravity

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

What is the name for a push or pull?

• A movement
• A force
• Speed
• Density

Which type of force(s) will cause a change in an object's motion?

• gravity
• zero net force
• balanced forces
• unbalanced forces

friction is a force that acts 

• in the same direction as the motion
• opposite to the direction of the motion
• opposite to the applied forces
• the same direction as the applied force

What is Newton's First Law

• F=ma
• Every action has an equal and opposite reaction
• An object at rest stays at rest, an object in motion stays in motion. 
• Friction 

When an unbalanced force pushes against an object what happens

• will change velocity

• change speed and direction

• Increase its mass

• Nothing

What it the equation for the second law of motion

• F/m=a

• M/FV

• F=MA

• M=AF

______ is the rate at which your velocity changes?

• Acceleration

• Mass

• Direction

• Velocity

What is an unbalanced force? two objects where...

• One has more force than the other

• they both have equal forces

• They have no forces
