Newton
Who discovered gravity?
Sir Isaac Newton
What type of energy is related to gravity?
Which one of newtons laws has to do with force and motion?
Newtons 2nd law.
Define mass.
The amount of matter an object has.
Name one thing that can slow down objects.
Friction or air resistance.
What is Force measured by?
Newtons
Does gravity push?
No, it pulls.
Define force.
The push or pull of an object.
If an astronaut goes to the moon how will his weight change?
Less gravity will be pulling him due to less gravity on the moon.
How does a plane slow down?
Air resistance.
What is newtons 1st law?
Inertia
What is gravity?
The force pushing things to the ground.
What is the speed calculation?
s=d/t
Mass is a ______?
Constant.
What does friction produce?
Heat.
What is newtons third law?
If you apply Force there will always be an equal and opposite reaction.
What can gravity be measured by?
Weight.
What is the calculation for force?
f=m*a
Whats the difference between mass and weight?
Mass is the amount of matter something has and weight is the amount of gravity pulling on it.
Define friction.
The resistance that one surface or object encounters when moving over another?
What is newtons second law?
The acceleration of an object is directly proportional to the net force acting upon it.
What is the bending of gravity in space called?
Space time.
Define Inertia.
The tendency of matter to resist a change in motion.
If a 135 pound man jumps on a trampoline with net force of 500 pounds, how high will he go.
I ain't doin all that.
If a very muscular man runs and scrapes his big toe nail on the cement what would that result in?
Pain or friction for you nerds.
