What is the standard unit force is measured in?

• Newtons
• pounds
• grams
• meters

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

• Friction
• Mass
• Inertia
• Gravity

What is Newton's Third Law?

• Object in motion stays in motion and an object at rest stays at rest unless acted on by a outside force
• Force = mass x acceleration
• For every action there is an equal and opposite reaction

According to Newton's second law, if you increase the force applied to an object :

• it accelerates more
• it doesn't move
• you get more inertia
• it decelerates

Newton's first law of motion states that __________.

• when a force is applied on an object, there is an equal force applied by the object in the opposite direction
• hen a force acts on an object, its acceleration is in the same direction as the force
• an object will remain at rest or keep moving with a constant velocity unless a force acts on it
• cceleration is calculated by dividing the force exerted on an object by the mass of the object

As the wheels of a train push down on the track, the track pushes back against the wheels. Which of Newton's laws is used to explain these forces.

• An object at rest tends to stay at rest unless acted upon by an unbalanced force.
• The net force of an object is its mass times its acceleration.
• For every action, there is an equal and opposite reaction.
• Any 2 objects exert a gravitational force of attraction on each other.

A truck that is travelling at a constant speed is carrying some boxes.  If the truck comes to a sudden stop, what will most likely happen to the boxes?

• They will stay in the middle of the truck.
• They will slide toward the front of the truck.
• They will slide toward the back of the truck.
• They will fall off the side of the truck.

A student throws a ball against a wall.  Which statement best explains what is happening in the picture.

• The energy of the ball is destroyed as it strikes the wall.
• The energy of the ball becomes negative as it hits the wall.
• The force from the wall on the ball is equal and opposite to the force from the ball on the wall.
• The force exerted by the ball on the wall is greater than the force exerted by the wall on the ball.
