Newton's law

What is a PUSH or PULL of an object?

• Motion
• Force
• Friction
• Gravity

For every action, there is an equal and opposite reaction.

  3rd
  Law of Motion

Newton's Third Law States...

• Objects in motion stay in motion and objects at rest stay at rest
• Force is equal to mass times acceleration
• For each action there is an equal and opposite reaction

A baseball player bats a ball with a force of 1,000 N. The ball exerts a reaction force (without any additional forces action on it) against the bat of...

• Less than 1, 000 N
• 1,000 N
• More than 1,000 N

What is the reaction force to a foot pushing down on the floor?

• The foot going through the floor
• The floor pushing back against the foot
• The floor breaking to the foot

Inertia is the resistance of an object to a change in its

• gravity

• motion

• mass

• balanced force

What is inertia?

• he opposing force of gravity.

• Another name for unbalanced forces.

• The tendency of an object to continue doing what it is currently doing.

• The mass of an object.

According to Newton’s second law of motion, if force remains the same but mass increases, then acceleration will

• increase

• decreases

• remain constant

A change in velocity over time is called ___________.

• speed
• force
• acceleration
• direction

According to __________, the acceleration of an object is equal to the net force acting on the object divided by the object's mass.
