Balanced and Unbalanced Forces

Front

What is an unbalanced force?

Back

An unbalanced force is when two forces acting on an object are not equal in size, causing a change in motion.

Front

What is the net force when two forces of 35 N and 25 N are acting in the same direction?

Back

The net force is 60 N to the right.

Front

What is an example of balanced forces?

Back

An asteroid moving at a constant speed through space is an example of balanced forces.

Front

What happens when two teams pull with the same amount of force?

Back

If two teams pull with the same amount of force, they will not move at all.

Front

What describes the forces acting on a wheeled cart moving at a constant speed with equal forces?

Back

The forces are balanced, and the cart maintains a constant speed.

Front

Define balanced forces.

Back

Balanced forces are two or more forces acting on an object that are equal in size and opposite in direction, resulting in no change in motion.

Front

What is the effect of unbalanced forces on an object's motion?

Back

Unbalanced forces cause an object to accelerate, change direction, or change speed.

Front

How can you determine if forces are balanced or unbalanced?

Back

If the net force is zero, the forces are balanced; if the net force is not zero, the forces are unbalanced.

Front

What is the formula for calculating net force?

Back

Net force is calculated by adding or subtracting all the forces acting on an object, depending on their direction.

Front

What is inertia and how does it relate to balanced forces?

Back

Inertia is the tendency of an object to resist changes in its state of motion; balanced forces keep an object at rest or moving at a constant speed.
