Acceleration-speed up, slow down changing to 

a new direction. For example, a airplane 

accelerates to take off to fly.

Battery-This is a battery that has charges and 

gives power.

Charge-A charge is a electric energy stored in a 

battery. There are positive and negative charges in a 

battery.

    Positive                                          Negative

Distance-It's the amount of space between 2 things or 

people. For example, the boy and girl have a distance 

between them.

Electric circuit-a path that carries electrical energy. 

For example your door bell is connected to a voice 

box in your house, that has a electric circuit.

Force- A force is a push or pull.Also,It's calculated in 

Newtons. For example It takes force to ride a bike.

Gravitational Potential Energy-It's the energy an 

object possesses because of it's position in an 

gravitational field. For example-The apple tree 

has Gravitational potential 

energy because an apple 

can fall off at any second.

Horsepower-is a unit of power that's equal to 745.7 

watts. For example,It's also 550 foot-pound per 

second, so named as this is

 how much a horse can lift.

Inertia- is the tendency to remain either in motion 

or at a stop. Ex: The relay racer is running and can 

stop whenever he wants.

Joule- It's a measurement of energy equal to the 

work done by one newton across one meter. A joule 

calculates work and kinetic energy.

Kinetic energy- It's the energy of motion. All things 

in motion have Kinetic energy. Ex: A ball in that is 

still moving.

Law of Conservation of Energy-It's the energy that 

can not be created nor can it be destroyed. Ex: A 

light bulb will never go out because of the Law of 

Conservation of energy.

Momentum-It's the quantity of motion on a 

moving body.It's equation is 

Momentum=mass*velocity.

Ex: This runner has 

momentum.

Newton-It's a measurement of force needed to 

move 1 kilogram.Ex: Someone working for the 

UPS would need to

use a lot of newton to 

lift this. 

Ohm-The unit of electrical resistance. Also it's  

the electrical resistance force.This crate is using a 

lot of ohm.

Potential Energy-the amount of stored energy an 

object has. For Example, This soccer ball has a lot 

of potential energy because of it's height.
