Representing Forces

Front

What is a force?

Back

A push or pull exerted on an object.

Front

What is net force?

Back

The sum of all forces acting on an object and the direction of that sum.

Front

What does friction do to a moving object?

Back

Friction opposes the motion of a moving object, causing it to slow down or stop.

Front

What is the direction of a force?

Back

The direction in which the force is applied, represented by an arrow in force diagrams.

Front

What is an unbalanced force?

Back

When the forces acting on an object are not equal in size and opposite in direction, causing a change in motion.

Front

What is a balanced force?

Back

When two forces acting on an object are equal in size and opposite in direction, resulting in no change in motion.

Front

How can you determine the net force acting on an object?

Back

By adding all the forces acting on the object, taking into account their directions.

Front

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

Back

The object remains at rest or continues to move at a constant speed in a straight line.

Front

What is the effect of applying a force to a stationary object?

Back

It can cause the object to start moving, depending on the magnitude and direction of the force.

Front

What is the role of arrows in force diagrams?

Back

Arrows represent the direction and magnitude of forces acting on an object.
