Balanced and Unbalanced Forces

Front

What is a Balanced Force?

Back

A balanced force occurs when two or more forces acting on an object are equal in size but opposite in direction, resulting in no change in motion.

Front

What is an Unbalanced Force?

Back

An unbalanced force occurs when two or more forces acting on an object are not equal, causing the object to accelerate in the direction of the net force.

Front

Example of Balanced Force: A lamp sitting on a table.

Back

The forces acting on the lamp (gravity pulling it down and the table pushing it up) are equal, resulting in no movement.

Front

Example of Unbalanced Force: A rocket lifting off the launch pad.

Back

The force of thrust from the rocket engines is greater than the gravitational force, causing the rocket to accelerate upward.

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 Net Force?

Back

Net force is the vector sum of all the forces acting on an object, determining the object's acceleration.

Front

Calculate the Net Force: 40N to the left and 40N to the right.

Back

0N, Balanced (the forces cancel each other out).

Front

Calculate the Net Force: 75N to the right and 40N to the left.

Back

35N to the right (the right force is greater).

Front

What is the effect of an unbalanced force on a stationary object?

Back

An unbalanced force will cause the stationary object to start moving in the direction of the force.

Front

What is the effect of an unbalanced force on a moving object?

Back

An unbalanced force will change the speed or direction of the moving object.
