8.6A Net Forces and FMA

Front

What is a net force?

Back

The net force is the overall force acting on an object when all the individual forces are combined. It determines the object's motion.

Front

What does it mean if forces are balanced?

Back

Balanced forces mean that the total net force acting on an object is zero, resulting in no change in motion.

Front

What does it mean if forces are unbalanced?

Back

Unbalanced forces result in a net force that is not zero, causing the object to accelerate in the direction of the net force.

Front

If two forces act in the same direction, how do you find the net force?

Back

The net force is the sum of the two forces acting in the same direction.

Front

What is Newton's 3rd Law of Motion?

Back

For every action, there is an equal and opposite reaction. This means forces always act in pairs.

Front

What is the unit of force?

Back

The unit of force is the Newton (N).

Front

What happens to an object when a net force is applied?

Back

The object will accelerate in the direction of the net force according to Newton's second law.

Front

What is the formula for calculating net force?

Back

Net Force (F_net) = mass (m) × acceleration (a).

Front

What is an example of unbalanced forces in everyday life?

Back

A car accelerating when the driver presses the gas pedal is an example of unbalanced forces.

Front

What is an example of balanced forces?

Back

A book resting on a table is an example of balanced forces; the force of gravity is balanced by the normal force from the table.
