With action- reaction forces, ________.

• The reaction force is created first
• The action force is created first
• The forces are created at the same time
• Both forces already existed

A push or a pull is known as

• Motion
• Force
• Acceleration
• Velocity

Inertia

• depends on direction
• depends on momentum
• resists a change in motion of an object
• both a and b

Mr. Bolt runs the 100m dash in 9 seconds. We could use this information to calculate his

• Position
• Motion
• Speed
• Acceleration

Franklin is given a certain speed he must travel and he is told he must travel north. This is an example of a

• Mass
• Position
• Direction
• Velocity

John combines all forces acting on a soccer ball. He is finding the

• Inertia
• Contact force
• Gravitational Force
• Net Force

Inertia is the resistance of an object to change its

• Gravity
• Mass
• Balanced force
• Motion

According to Newton’s Second law, force equals mass times

• Mass
• Momentum
• Acceleration
• Velocity

When you push on your chair and the chair pushes back with an equal and opposite force, these forces are known as

• Mass and velocity pairs
• Unbalanced force pairs
• Mass and acceleration pairs
• Action/reaction pairs

George is moving a box across the floor. What does he need to know to calculate the force on the box?

• Mass and inertia
• Mass and acceleration
• Acceleration and friction
• Friction and gravity
