What is an attractive force between two objects with mass?
100
This is the name of the person who described the three laws we learned about in the Force and Motion unit.
Who is Isaac Newton?
100
This is the definition of a force.
What is any push or pull on an object?
100
This is the motion of an object expressed as the product of its mass and velocity.
What is momentum?
100
This is the amount of matter in an object.
What is mass?
200
This is the reason that gravity is stronger on the earth than on the moon.
What is that the strength of gravity depends on the mass of the object? OR What is that the earth is much bigger than the moon?
200
This is Newton's First Law of Motion.
What is "an object at rest will stay at rest and an object in motion will stay in motion unless acted upon by an outside (or more accurately an unbalanced) force."
200
This is the name of the force that points down in the free body diagram of any object on earth.
What is gravity or the force of gravity?
200
This is the momentum equation.
What is Momentum (p) = Mass (m) X Velocity (v)
200
This is the speed of an object in a defined direction.
What is velocity?
300
This is the direction that the arrow representing Fgravity always points on a free body diagram.
What is down?
300
This formula represents Newton's Second Law of Motion
What is Force (F) = Mass (m) X Acceleration (a)
300
This is the force that resists motion.
What is friction?
300
This is how much momentum a 300kg gorilla has when it is chasing you at 3m/s.
What is 900 kg*m/s?
300
This is the definition of inertia.
What is the tendency of an object to stay at rest or in motion unless acted upon by an outside force.
400
This is what object hits the ground first when you drop a feather and a hammer at the same time on the moon, where there is no air.
What is both hit at the same time?
400
This is Newton's Third Law of Motion
What is "for every action there is an equal and opposite reaction"
400
This is the name of the force applied by a stationary surface like my desktop which balances the force of gravity and points up in a free body diagram.
What is normal force?
400
Of a mouse, a person, or a train, this is the one which has the most momentum when all are traveling at the same speed.
What is a train?
400
This is one of two measurements which uses the Newton (N) as its unit.
What are weight and force?
500
This is the numerical value and units for "g" - the acceleration due to earth's gravity.
What is 9.8 m/s2?
500
This is the amount of force that will accelerate a 1kg mass at 1m/s2.
What is one Newton?
500
This is the amount of force required to accelerate a 60kg science teacher at 2 meters per second squared.
What is 120 Newtons?
500
This is the size of a person who has 400kg*m/s momentum when he is traveling at 5m/s?
What is 80kg?
500
This is the effect of gravity on the mass of an object.
