Newton's First Law
Which Law states that an object at rest will stay at rest?
Newton's first law
Which law defines the equation F=MA?
Newton's second law of motion.
Newton's third law of motion.
This causes touching objects to resist moving.
A non-moving object.
Balanced
Why does a bowling ball knock down the pins, and not the other way around?
The bowling ball has more mass, and therefore more force.
What would happen if you push against a wall while wearing roller blades?
You would move away with an equal amount of force to that which you pushed.
Which is greater friction? Rolling friction, or Sliding friction.
Sliding Friction
A car moving at a constant velocity.

What will happen to a potato moving 5m/s towards a small bump?
it will continue moving and bounce off.
The 1kg object.
What causes you to move forward when walking?
The ground pushes you forward when you push on the ground.
Why is it easier to pull a box on the ground instead of pushing it?
It lowers the surface area of the box, and less force into the ground, which is less friction.
A car moving at a constant speed, but is getting blown by wind to the left.
Unbalanced
What will an object do if acted upon by an unbalanced force?
It will move.
If it takes 1 newton to move a 1 kg object 1 meter, and 5 newtons to move a 5kg object 5 meters, how many newtons would it take to move a 7kg object 21m?
21 newtons.
What happens when a pinball hits a rubber bumper?
It bounces off with equal and opposite force.
What would happen if a skateboard had no wheels, and you tried skating?
The board probably wouldn't move because there would be too much friction.
A plane falling out of the sky at 9.8m/s
balanced.
What will happen to a person not wearing a seatbelt if they slam on the brakes?
They will likely fly through the front windsheild.
The clown car would accelerate faster, because it has less mass.
Why is is bad to drive into a wall?
The wall will exert a equal and opposite force into you.
What would happen if there was no friction when you slam on the brakes while going fast in a car?
You would continue going at the same speed more or less. (Minus Drag and air resistance)
A 10m long seesaw on top of a car moving 6m/s/s north with the fulcrum located 2 feet from one end with a bowling ball on it, and on the other end there is a tennis ball.
