Force and Motion Test Review

Front

What is acceleration?

Back

Acceleration is the rate at which an object changes its velocity. It can mean speeding up, slowing down, or changing direction.

Front

What is an unbalanced force?

Back

An unbalanced force is a force that causes an object to change its motion. It is not equal in size and opposite in direction to other forces acting on the object.

Front

What is velocity?

Back

Velocity is the speed of an object in a specific direction.

Front

What is kinetic energy?

Back

Kinetic energy is the energy an object has due to its motion. It depends on the mass and speed of the object.

Front

What is the difference between speed and velocity?

Back

Speed is how fast an object is moving, while velocity includes both speed and direction.

Front

What does a flat line on a distance-time graph represent?

Back

A flat line on a distance-time graph represents no motion; the object is at rest.

Front

What does a steep slope on a distance-time graph indicate?

Back

A steep slope on a distance-time graph indicates a high speed; the object is moving quickly.

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 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 an unbalanced force.

Front

What is gravitational force?

Back

Gravitational force is the attraction between two objects due to their mass. It pulls objects toward each other.
