Newton's First Law of Motion

Front

ex. when a car suddenly stops and your head continues to move foward even though your body is stopped by the seat belt

Back

distance

Front

How far an object moves

Back

Law of Conservation of Energy

Front

energy can neither be created nor destroyed; energy just changes form

Back

Convection

Front

the transfer of thermal energy by the circulation or movement of a liquid or gas

Back

Kinetic Energy

Front

energy of motion

Back

Acceleration

Front

how speed changes with time; can be positive (speeding up) or negative (slowing down); change in speed/time

Back

Average Speed

Front

the total distance traveled by an object in a given amount of time; rate of motion; distance/time

Back

Thermal Energy

Front

energy in the form of heat

Back

Newton's First Law of Motion

Front

an object at rest will stay at rest unless acted upon by an outside force; an object in motion will stay in motion unless acted upon by an outside force

Back

Velocity

Front

speed of an object and its direction of motion; changes when speed, direction or both changes

Back

Joule

Front

unit of work

Back

light energy

Front

Energy in the form of moving waves of light

Back

sound energy

Front

energy carried by sound waves

Back

mechanical energy

Front

kinetic energy + potential energy

Back

Work

Front

force exerted on an object that causes the object to move in same direction that the force was applied

Back

Chemical Energy

Front

energy stored in the bonds of molecules and compounds (all living and once living things)

Back

friction

Front

the resistance that one surface or object encounters when moving over another.

Back

Conduction

Front

the direct transfer of heat from one substance to another substance that it is touching

Back

Force

Front

push or pull; causes objects to move

Back

Inclined plane

Front

a ramp used to reduce the effort needed to raise or lower an object over a vertical height.

Back

Wind Energy

Front

converts the movement of wind into electric energy

Back

Inertia

Front

the tendency of a body to maintain is state of rest or uniform motion unless acted upon by an external force

Back

Newton's Second Law of Motion

Front

ex. the force applied to a roller coaster car in addition to the mass of the car determines the acceleration of the car; more force = more acceleration

Back

Newton's Third Law of Motion

Front

ex. as the thrust of a rocket pushes down on Earth's surface, the rocket launches upward into the atmosphere

Back

Gravity

Front

A force of attraction between objects that is due to their masses.

Back

air resistance

Front

force that opposes the motion of objects that move through the air

Back

Electrical Energy

Front

energy of moving electrons

Back

Net Force

Front

The combination of all forces acting on an object

Back

newton

Front

the unit of force, mass times acceleration.

Back

motionless

Front

not moving; stationary

Back

Newton's Second Law of Motion

Front

the greater the force applied to an object, the greater the acceleration; the smaller the mass of an object, the greater its acceleration when force is applied; only an unbalanced force can cause objects to accelerate

Back

Unbalanced Force

Front

change speed or direction of object's motion; not equal and opposite

Back

Hydroelectric Energy

Front

Electricity generated from the force of moving water

Back

Balanced Force

Front

do not cause a change in motion; equal in size and opposite in direction; cancel each other out

Back

Motion

Front

any physical movement; change in position or place

Back

Potential Energy

Front

energy stored or energy of position

Back

Newton's Third Law of Motion

Front

for every action there is an equal and opposite reaction; forces act in pairs

Back

Solar Energy

Front

Energy from the sun

Back

Energy

Front

the ability to do work or cause a change

Back
