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 do you calculate net force when forces are in opposite directions?

Back

You subtract the smaller force from the larger force.

Front

How do you calculate net force when forces are in the same direction?

Back

You add the magnitudes of the forces together.

Front

What is the formula for calculating acceleration?

Back

Acceleration = Net Force / Mass.

Front

If a box has a mass of 5 kg and a net force of 35 N acting on it, what is the acceleration?

Back

Acceleration = 35 N / 5 kg = 7 m/s².

Front

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

Back

The object remains at rest.

Front

What happens to a moving object when unbalanced forces act on it?

Back

The object will change its velocity, either speeding up, slowing down, or changing direction.

Front

What is the unit of force?

Back

The unit of force is the Newton (N).

Front

If two forces of 10 N and 15 N act in the same direction, what is the net force?

Back

Net Force = 10 N + 15 N = 25 N.
