What are balanced forces?

Back

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

Front

What are unbalanced forces?

Back

Unbalanced forces occur when two or more forces acting on an object are not equal, causing the object to accelerate in the direction of the net force.

Front

What is net force?

Back

Net force is the overall force acting on an object after all the individual forces are combined. It determines the object's acceleration.

Front

How does friction affect motion?

Back

Friction is a force that opposes motion between two surfaces in contact. It can slow down or stop moving objects.

Front

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

Back

An object at rest will remain at rest when balanced forces act on it.

Front

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

Back

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

Front

If a cart is moving to the right at a constant speed, what can we say about the forces acting on it?

Back

The forces acting on the cart are balanced, resulting in constant speed.

Front

Calculate the net force when two forces of 20 N right and 30 N left act on an object.

Back

Net force = 20 N right - 30 N left = 10 N left.

Front

What is the effect of unbalanced forces on a stationary object?

Back

Unbalanced forces will cause a stationary object to start moving in the direction of the net force.

Front

If a person pushes a box with 50 N to the right and another person pushes with 30 N to the left, what is the net force?

Back

Net force = 50 N right - 30 N left = 20 N right.
