The ability to do work or cause change; the ability to move an object some distance
A pull or push that is applied to an object
force
Energy that comes from the sun
Solar Energy
Energy in the form of heat
Thermal Energy
Name one thing you have learned in science this year?
Answers will vary
The energy an object has because of its motion
kinetic energy
A force applied to an object over a distance
work
Energy stored due to position in a gravitational field; commonly due to Earth's gravity
Gravitational Potential Energy
A car travels a distance of 120 miles in 2 hours. What is the average speed of the car?
120/2=60 mph
An athlete runs a 4-mile route in 30 minutes. What is their average speed in miles per hour (mph)?
4x2=8 mph
The amount of matter in an object
mass
A change in the position of an object compared to another object (related term: move, movement)
motion
The energy that is stored in the bonds between atoms
chemical energy
The amount of energy that is stored in an object; energy that an object has because of its position relative to other objects
Potential Energy
A cyclist covers a distance of 450 meters in 30 seconds. What is the speed of the cyclist in meters per second (m/s)?
450/30=15 m/s
The result of two objects hitting one another
collision
A force that opposes the motion of a body across a surface or through a gas or liquid
friction
A force that exists between any two objects that have mass (related word: gravitational)
gravity
The energy released when the nucleus of an atom is split apart (during fission) or combined with another nucleus (during fusion)
Nuclear Energy
A train travels a distance of 240 kilometers in 3 hours at a constant speed. What is the speed of the train?
240/3=80 kph
A change in the velocity (speed, direction, or both) of a body (related word: accelerate)
acceleration
What is the speed equation?
Speed = Distance/Time
The tendency of materials to not transfer energy
resistance
Energy cannot be created out of nothing, nor can it be completely destroyed. Energy can only change its form.
Conservation of Energy
A double bicycle rider travels a total distance of 24 miles over a span of 2 hours. What was the rider's average speed?
24/2=12 mph
