Unbalanced/Balanced Forces 2020.21

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

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

Back

The object remains at rest or continues to move at a constant speed in a straight line.

Front

What happens to an object when unbalanced forces act on it?

Back

The object will 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

If two forces of 400 N are acting in opposite directions, what is the net force?

Back

The net force is 0 N (balanced forces).

Front

If a force of 600 N is acting to the right and a force of 400 N is acting to the left, what is the net force?

Back

The net force is 200 N to the right (unbalanced force).

Front

What is the effect of a net force of zero on an object?

Back

An object with a net force of zero will not change its state of motion.

Front

How do you determine the direction of the net force?

Back

The direction of the net force is the same as the direction of the larger force when forces are unbalanced.

Front

What is inertia?

Back

Inertia is the tendency of an object to resist changes in its state of motion.
