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 the forces acting on an object are not equal, causing the object to accelerate in the direction of the net force.

Front

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

Back

The object will start to move, change direction, or change speed.

Front

If an object is stationary, what can we say about the forces acting on it?

Back

The forces acting on it are balanced.

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 two forces are acting in the same direction?

Back

You add the magnitudes of the two forces together.

Front

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

Back

You subtract the smaller force from the larger force.

Front

What is the unit of force?

Back

The unit of force is the Newton (N).

Front

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

Back

An object with a net force of zero will remain at rest or continue to move at a constant velocity.

Front

What is inertia?

Back

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