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

How does an object move when unbalanced forces act on it?

Back

An object will accelerate in the direction of the net force when unbalanced forces act on it.

Front

What is net force?

Back

Net force is the overall force acting on an object after all the individual forces are combined.

Front

If the net force is 0N, what can we say about the forces acting on the object?

Back

The forces acting on the object are balanced.

Front

Give an example of balanced forces in everyday life.

Back

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

Front

What happens to an object in motion when balanced forces act on it?

Back

An object in motion will continue to move at a constant speed in a straight line when balanced forces act on it.

Front

Describe the motion of the moon orbiting the Earth.

Back

The moon orbiting the Earth at a constant speed is an example of balanced forces, as gravitational pull and centripetal force are in balance.

Front

What is the effect of unbalanced forces on a skier racing down a mountain?

Back

The skier experiences unbalanced forces, which cause them to accelerate down the slope.

Front

How can you calculate net force?

Back

To calculate net force, add all the forces acting on an object, taking into account their direction.
