What is energy transfer?

Back

Energy transfer is the process of moving energy from one place to another or changing it from one form to another, such as from electrical energy to kinetic energy.

Front

What is kinetic energy?

Back

Kinetic energy is the energy an object has due to its motion. The faster an object moves, the more kinetic energy it has.

Front

What is potential energy?

Back

Potential energy is the stored energy in an object due to its position or state. For example, a ball held at a height has potential energy.

Front

What is friction?

Back

Friction is a force that opposes the motion of an object. It occurs when two surfaces rub against each other.

Front

What is applied force?

Back

Applied force is the force that is applied to an object by a person or another object, causing it to move or change its motion.

Front

What is gravity?

Back

Gravity is the force that pulls objects toward each other, such as the force that pulls objects toward the Earth.

Front

How does pushing a ball change its energy?

Back

Pushing a ball increases its motion, which increases its kinetic energy.

Front

What is motion?

Back

Motion is the change in position of an object over time. It can be described in terms of speed and direction.

Front

What is a drone?

Back

A drone is an unmanned aircraft that can fly and is often controlled remotely. It uses energy to move through the air.

Front

How can energy transfer be used in sports?

Back

Energy transfer can be used in sports, such as when a player hits a baseball, transferring energy from the bat to the ball.
