100
A push or a pull
What is a force
100
You use a timer and a ruler to measure this.
What is speed.
100
A roller coaster at the top of a hill has lots of it.
What is potential energy
100
An object at rest stays at rest.
What is inertia
100
Newton's Second Law
What is acceleration of an object depends upon the force acting on the object and the mass of the object.
200
measures force in units called Newtons
What is a spring scale
200
The energy of objects in motion
What is kinetic energy
200
The ability of do work.
What is energy
200
These are used in a car to counter act inertia and keep passengers safe.
What are seat belts
200
To move a more massive object, you need more of this.
What is force.
300
You need this much force to lift an apple
What is one newton
300
Rate a which the velocity of an object changes.
What is acceleration
300
Energy made by using the sun's heat.
What is solar energy.
300
Unless it is acted upon by a force, this would stay in motion.
What is an object in motion
300
This will happen to its acceleration if you reduce the mass of a car.
What is accelerate more.
400
Motion is stopped and started by this
What is forces
400
Rate of speed and direction of motion.
What is velocity
400
A battery that has not been used has lots of this.
What is potential energy
400
Something that causes an object at rest to move.
What is a force
400
Mass times acceleration equals this.
What is force
500
You need about one of these to lift an apple
What is a newton
500
Speed that a car is going when is travels 300 miles in 3 hours.
What is 100 miles per hour.
500
A ball rolling down a hill, turns potential energy into this.
What is kinetic energy
500
Acceleration depends on the amount of this.
What is force
500
Acceleration equals force divided by this.
What is mass.
