Balanced and 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 accelerate in the direction of the greater force.

Front

Example of balanced forces in everyday life?

Back

A lamp sitting on a table is an example of balanced forces because the force of gravity pulling it down is balanced by the table pushing it up.

Front

Example of unbalanced forces in everyday life?

Back

A car accelerating around a mountain curve is an example of unbalanced forces because the force of the engine is greater than the friction opposing it.

Front

What force causes objects to fall to the ground?

Back

Gravity is the force that causes objects, like an egg, to fall to the ground.

Front

What happens in a tug of war when both teams pull with the same force?

Back

If both teams pull with the same amount of force, neither team will move, resulting in balanced forces.

Front

What is the effect of gravity on falling objects?

Back

Gravity pulls objects towards the Earth, causing them to accelerate downwards.

Front

How can you tell if forces are balanced or unbalanced?

Back

If an object is at rest or moving at a constant speed, the forces are balanced. If the object is accelerating, the forces are unbalanced.

Front

What is an example of an unbalanced force in sports?

Back

In football, when a player pushes another player, the force is unbalanced, causing the pushed player to move.

Front

What happens to an object at rest when unbalanced forces act on it?

Back

An object at rest will start to move in the direction of the greater force when unbalanced forces act on it.
