Bal/Unbal Forces + Net Force

Front

What is a balanced force?

Back

Balanced forces are two or more forces acting on an object that cancel each other out, resulting in no change in motion.

Front

What is an unbalanced force?

Back

Unbalanced forces occur when two or more forces acting on an object do not cancel each other out, 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.

Front

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

Back

Add the magnitudes of the forces together.

Front

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

Back

Subtract the smaller force from the larger force and take the direction of the larger force.

Front

What happens to an object when the net force is zero?

Back

The object remains at rest or continues to move at a constant velocity.

Front

What is the unit of force?

Back

The unit of force is Newton (N).

Front

If a marble rolls down a ramp, what type of forces are acting on it?

Back

Unbalanced forces are acting on the marble, causing it to accelerate down the ramp.

Front

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

Back

Balanced forces do not change the object's motion; it remains at rest or continues moving at a constant speed.

Front

If two forces of 30N and 40N act in the same direction, what is the net force?

Back

The net force is 70N in the same direction.
