A force is a ______________ or a ____________ on something

What is a push or a pull?

100

This is the equation for speed.

What is speed = distance/time

100

This is what Newton's First Law tells us.

An object in motion will stay in motion unless acted upon by an unbalanced force, and an object at rest will stay at rest unless acted upon by an unbalanced force.

100

This is the kind of energy contained in moving things.

What is kinetic energy?

200

This is the unit we use to measure force

What is a Newton?

200

Velocity is speed with ________________.

What is direction?

200

This the word we use for the tendency of an object to resist a change in its state of motion.

What is inertia?

200

This is an example of something that takes energy but doesn't count as work in physics.

Answers will vary

200

This is the kind of energy that is stored in an object because of its position, chemical makeup, or elasticity.

What is potential energy?

300

This is the name for the kind of force that comes from one thing touching another

What is a contact force?

300

This is the rate of change in velocity over time.

What is acceleration

300

This is what Newton's Second Law tells us.

Net force = mass x acceleration

300

This is the unit we use to measure work

What is a joule?

300

This is what the Law of Conservation of Energy tells us.

Energy cannot be created or destroyed.

400

This is an example of a non-contact force.

What is gravity, magnetism, strong nuclear force, or weak nuclear force?

400

This is the speed of an object that travels 156 meters in 12 seconds

What is 13 m/s?

400

This is what Newton's Third Law tells us

For every action there is an equal and opposite reaction

400

This is the equation for work.

What is work = force x distance

400

These are the kinds of energy we see at work in a campfire

What are chemical energy, thermal energy, and radiant energy?
500
This is what we call all of the forces acting on an object added together.

What is net force?

500

This is the acceleration of an object that starts off traveling at 20 m/sec. and ends up traveling 40 m/sec. after 10 seconds.

What is 2 m/sec2

500
In a vacuum, gravity will accelerate an object toward Earth at this rate.

What is 9.8 m/sec.2

500

This is the amount of work done over a specific period of time.

What is power?
