Types of Motion

Front

What is a balanced force?

Back

A balanced force is when two forces acting on an object are equal in size but opposite in direction, resulting in no change in motion. Example: A book resting on a table.

Front

What happens when the net force on an object is zero?

Back

When the net force on an object is zero, there is no change in motion. The object remains at rest or continues to move at a constant speed.

Front

What is acceleration?

Back

Acceleration is the rate at which an object changes its velocity. It can occur when an object speeds up, slows down, or changes direction.

Front

What is speed?

Back

Speed is the distance traveled per unit of time. It is a scalar quantity and does not include direction. Example: A dog runs at 9 mi/hr.

Front

What is velocity?

Back

Velocity is the speed of an object in a specific direction. It is a vector quantity. Example: A car moving east at 60 km/h.

Front

What is the difference between speed and velocity?

Back

Speed is a scalar quantity that measures how fast an object is moving, while velocity is a vector quantity that includes both speed and direction.

Front

What is an example of changing direction?

Back

An example of changing direction is a car making a left turn while driving.

Front

What is the formula for calculating acceleration?

Back

Acceleration = (Final Velocity - Initial Velocity) / Time.

Front

What is a force?

Back

A force is a push or pull acting on an object. It can cause an object to accelerate, change direction, or change shape.

Front

What is the unit of force?

Back

The unit of force is the Newton (N).
