Potential vs Kinetic Energy MS-PS3-1

Grade 8 - NGSS - CA

A change in velocity with respect to time

Acceleration

A change in velocity with respect to time. Acceleration. Acceleration is how quickly something speeds up, slows down, or changes direction.

The tendency of objects to resist any change in motion

Inertia

The tendency of objects to resist any change in motion. Inertia. Inertia means that objects will keep doing what they're doing, like staying still or moving, unless something else makes them change.

The energy of a moving object

Kinetic energy

The energy of a moving object. Kinetic energy. Kinetic energy is the energy an object has because of its motion.

The amount of matter in an object

Mass

The amount of matter in an object. Mass. Mass is how much stuff or material is inside an object.

The product of an object's mass and velocity

Momentum

The product of an object's mass and velocity. Momentum. Momentum is how much motion something has and how hard it is to stop it.

The energy an object has from its position or condition, like a ball on a hill or a stretched spring

Potential energy

The energy an object has from its position or condition, like a ball on a hill or a stretched spring. Potential energy. Potential energy is stored energy that can be released when an object's position or condition changes.

The distance an object travels per unit of time

Speed

The distance an object travels per unit of time. Speed. Speed is how fast something moves from one place to another.

Speed and direction of a moving object

Velocity

Speed and direction of a moving object. Velocity. Velocity is how fast something is moving and in which direction.
