Energy, Force, and Motion

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 inertia?

Back

Inertia is the tendency of an object to resist changes in its state of motion. An object at rest stays at rest, and an object in motion stays in motion unless acted upon by a force.

Front

What is direction in terms of motion?

Back

Direction refers to the line or path along which something moves. It indicates where an object is heading.

Front

What is potential energy?

Back

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

What is kinetic energy?

Back

Kinetic energy is the energy of an object in motion. The faster an object moves, the more kinetic energy it has.

What is speed?

Back

Speed is the distance traveled per unit of time. It tells us how fast an object is moving.

Front

What is velocity?

Back

Velocity is the speed of an object in a specific direction. It includes both the speed and the direction of motion.

Front

What does a distance-time graph show?

Back

A distance-time graph shows how the distance of an object changes over time. It can indicate whether the object is moving, stationary, or returning to its starting point.

Front

What happens to an object when a force is applied?

Back

When a force is applied to an object, it can cause the object to accelerate, change direction, or change shape.

What is friction?

Back

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