Balanced & Unbalanced Forces

Front

What is a balanced force?

Back

A balanced force occurs when two 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 forces acting on an object are not equal, causing the object to move in the direction of the stronger force.

Front

What force pulls objects towards the Earth?

Back

The force of gravity pulls objects towards the Earth.

Front

What happens to a ping-pong ball when gravity acts on it?

Back

The ping-pong ball falls downwards due to the force of gravity.

Front

How can you change the direction of a moving object?

Back

You can change the direction of a moving object by applying a force in a different direction.

Front

What is an example of balanced forces in everyday life?

Back

An example of balanced forces is a book resting on a table; the force of gravity pulling it down is balanced by the support force from the table.

Front

What is an example of unbalanced forces in sports?

Back

An example of unbalanced forces in sports is when a player pushes a ball; the force they apply is greater than the friction, causing the ball to move.

Front

What role does air pressure play in the movement of a ping-pong ball?

Back

Air pressure can affect the movement of a ping-pong ball, but gravity is the main force that pulls it down.

Front

What is the direction of force?

Back

The direction of force is the way in which the force is applied, which can change the motion of an object.

Front

What happens when forces are balanced?

Back

When forces are balanced, the object remains at rest or continues to move at a constant speed in a straight line.
