What does Newton's first law of motion state?
For every action there is an equal and opposite reaction
The larger the mass of an object the more force needed to move it? F=ma
An object at rest tends to stay at rest and an object in motion tends to stay in motion in the same direction and at the same speed unless acted upon by an unbalanced force.
What does Newton's second law of motion state?
For every action there is an equal and opposite reaction
The larger the mass of an object the more force needed to move it? F=ma
An object at rest tends to stay at rest and an object in motion tends to stay in motion in the same direction and at the same speed unless acted upon by an unbalanced force.
What does Newton's third law of motion state?
For every action there is an equal and opposite reaction
The larger the mass of an object the more force needed to move it? F=ma
An object at rest tends to stay at rest and an object in motion tends to stay in motion in the same direction and at the same speed unless acted upon by an unbalanced force.

balanced
unbalanced
What will be the effect on the boy in the picture if the driver stops quickly?
Because of inertia he will remain in the same position.
He will be pushed back into the car seat.
He will move from one side of the car seat to the other.
He will move forward pressing against the seatbelt.

Newton's Fourth Law of Motion
Sitting at the top of a steep hill on a roller coaster (not moving), is an example of:
Acceleration
Inertia
Speed
Velocity
Addie applies the same amount of force when she kicks a kickball and a cement wall. The kickball moves, but the cement wall does not move. Which of Newton's laws does this illustrate and why?
Newton's 1st law because force = mass x acceleration, so the kickball moves, but the wall does not.
Newton's 1st law because the action is the wall/ball, the reaction in Addie's foot kicking.
Newton's 2nd law, because it will require more force to move the brick wall because it has more mass.
Newton's 3rd law, because force = mass x acceleration.
Grissom jumps off a diving board. When he hits the water, he continues to move downward, but a large amount of water moves up in a huge splash. Which of Newton's laws does this illustrate and why?
Newton's 2nd law, because his mass is high, so his acceleration is smaller to cause the same force.
Newton's 1st law because there is an equal and opposite reaction from the water.
Newton's 2nd law because the water will stay at rest.
Newton's 3rd law, because the action of him moving downward causes the reaction of the water moving up.
What does friction do to movement of a ball rolling on the ground?
It slows it down
It speeds it up
It does not impact motion
It causes gravity to increas
Mrs. Harding was driving to school when a deer runs in front of her car. She slams on the brakes in the car. Which concept explains why her coffee continues to move forward and spills everywhere when the car comes to a stop?
inertia
friction
velocity
gravity

50N, LEFT
50N, RIGHT
70N, LEFT
70N, RIGHT
What is the best example of Newton's Third Law of Motion?
A bowling ball siting at rest
A spaceship traveling at a constant speed in space
A metal 10 kg ball has more mass than a golf ball
When a baseball is hit, the ball pushes on the bat and the bat pushes on the ball
Which end of the balloon shows the ACTION force according to Newton's Third Law?
Air releasing out of the open end of the balloon
The closed end of the balloon
Dr. Evil created a machine that increases the force of gravity on Earth. Assuming that gravity is the only force that changes, how would this affect the velocity of your car?
it would decrease velocity because rolling friction increases
it would decrease velocity because acceleration increases
it would increase velocity because rolling friction would increase
it would increase velocity because wind friction increases

10 seconds
When you throw a basketball, your force on the ball accelerates it. The ball pushes back on you with an equal and opposite force. Why don't you accelerate as much as the ball?
The reaction force is only on your hand, not the rest of you
Friction stops you from acceleration
Your acceleration is much smaller than the ball's because of your larger mass
When a cannon fires a cannonball we observe Newton's third law. Which is the reaction force?
The cannon moving forward
the cannon moving backwards
the cannonball moving backwards
The cannonball moving forward
