What kind of energy is in a rock at the edge of a cliff?

Back

Potential energy is the energy stored in an object due to its position. A rock at the edge of a cliff has potential energy because of its height.

Front

A back-and-forth motion causing particles to move close together generates a _______.

Back

Compression is a region in a wave where particles are close together, resulting from a back-and-forth motion.

Front

Objects that allow ALL light to pass through are called _______.

Back

Transparent objects allow all light to pass through without scattering.

Front

What are the 3 fossil fuels?

Back

The three fossil fuels are natural gas, oil, and coal.

Front

What is a PUSH or PULL of an object?

Back

A force is any interaction that, when unopposed, will change the motion of an object.

Front

What is kinetic energy?

Back

Kinetic energy is the energy of an object in motion, calculated as 1/2 mv², where m is mass and v is velocity.

Front

What is the law of conservation of energy?

Back

The law of conservation of energy states that energy cannot be created or destroyed, only transformed from one form to another.

Front

What is a wave?

Back

A wave is a disturbance that transfers energy from one place to another without transferring matter.

Front

What is the difference between speed and velocity?

Back

Speed is a scalar quantity that refers to how fast an object is moving, while velocity is a vector quantity that includes both speed and direction.

Front

What is friction?

Back

Friction is the resistance that one surface or object encounters when moving over another, acting opposite to the direction of motion.
