Energy, Force, and Motion

Front

What is potential energy?

Back

Potential energy is the energy stored in an object due to its position or state. For example, a roller coaster at the top of a hill has high potential energy.

Front

What is acceleration?

Back

Acceleration is the rate at which an object changes its velocity. It can be a change in speed or direction.

Front

What is position?

Back

Position refers to the location of an object in space, often described in relation to a reference point.

Front

What are the three energy transformations when a rocket takes off?

Back

The three energy transformations are Chemical (fuel) - Thermal (heat from combustion) - Mechanical (movement of the rocket).

Front

How does mass affect stopping distance?

Back

A truck with a smaller mass will require less force to stop than a truck with a larger mass when both are traveling at the same speed.

Front

What is kinetic energy?

Back

Kinetic energy is the energy of an object in motion, which depends on its mass and speed.

Front

What is friction?

Back

Friction is the force that opposes the motion of an object when it comes into contact with another surface.

Front

What is gravity?

Back

Gravity is the force that attracts two bodies toward each other, commonly experienced as the force that pulls objects toward the Earth.

Front

What is speed?

Back

Speed is the distance traveled per unit of time, often measured in miles per hour (mph) or meters per second (m/s).

Front

What is velocity?

Back

Velocity is the speed of an object in a specific direction, combining both speed and direction.
