100
For an object to have momentum, it must have mass as well as this other quantity
What is velocity or speed?
100
This is how much your momentum changes if your mass is 4 kilograms, and your speed goes from 4 m/s to 10 m/s
What is 24 kg*m/s
100
These two quantities determine the amount of work that is done
What is force and distance?
100
This can be conceived as a transfer of energy between objects
What is work?
100
This law explains why effects such as gravity become weaker very rapidly as distance from the source increases
What is the inverse-square law?
200
This law states that the total momentum of a system remains the same when no net external force acts on it
What is the conservation of momentum?
200
If you experience a net force of 200 newtons for 11 seconds, you will have this much of an impulse
What is 2200 N*s
200
The ability to do work
What is energy?
200
The unit of power
What is the watt
200
This is the abbreviation for the gravitational constant
What is G?
300
Impulse- which is force times time- is equal to this other quantity
What is the change in momentum?
300
If two train cars of equal mass collide, with one of them at rest and the other traveling at 12 m/s, how fast will they be moving after the collision if they couple together?
What is 6 m/s?
300
Work divided by the time it took to do that work
What is power?
300
If you push a Chromebook cart with 200 newtons of force through 3 meters distance, this is how much power you used if it took you 6 seconds
What is 100 watts?
300
When a planet is disturbed from its course around the sun due to proximity with another planet
What is a perturbation?
400
For a given impact, the more you can extend the time of the hit, the less of this there will be
What is force?
400
A car experiences a change in momentum of 3000 units. If the net force that caused this change was 500 newtons, how long a time did the force act?
What is 6 seconds?
400
Gravitational potential energy requires this other quantity be multiplied by the weight of something
What is height?
400
A ramp providing a mechanical advantage of 2.5 is used to lift a 1000-N block of ice onto a loading dock. This will be the amount of input force needed
What is 400 newtons?
400
If the moon orbited six times as far from the Earth as it does now, this is how much the force of gravity on it would reduce
What is 36 times less (or 1/36th as much)
500
If heat is generated during an impact, you have this type of collision
What is an inelastic collision?
500
A 1000-kg car moving at 20 m/s slams into a building and comes to a halt. This is how much impulse acted on the car
What is 20,000 N*s?
500
If you are moving with 100 joules of kinetic energy, and your speed then becomes four times greater, this is your new kinetic energy
What is 1600 joules?
500
When do work on an object, you change its potential and/or kinetic energy
What is the work-energy theorem?
500
Two objects are both tripled in mass and then brought three times closer together (d becomes 1/3 d). This is how much stronger the force of gravity will be between them
What is 81 times stronger?
