Net Forces

Front

What is Potential Energy?

Back

Potential Energy is the energy stored in an object due to its position or state. For example, an archer's bow has potential energy when it is drawn back.

Front

What is Kinetic Energy?

Back

Kinetic Energy is the energy of an object in motion. For example, a baseball bat swinging through the air has kinetic energy.

Front

What does Newton's Third Law state?

Back

Newton's Third Law states that for every action, there is an equal and opposite reaction. This means forces always come in pairs.

Front

What is Net Force?

Back

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

Front

If two forces of 50 N and 30 N act in the same direction, what is the net force?

Back

The net force is 80 N in the direction of the forces.

Front

If a cart is pulled with a force of 100 N to the right and a force of 60 N to the left, what is the net force?

Back

The net force is 40 N to the right.

Front

What happens to an object if the net force acting on it is zero?

Back

If the net force is zero, the object will remain at rest or continue to move at a constant speed.

Front

What is the effect of increasing mass on acceleration when the same force is applied?

Back

Increasing mass will decrease the acceleration of the object when the same force is applied, according to Newton's second law (F=ma).

Front

What is the formula for calculating net force?

Back

Net Force (F_net) = Sum of all forces acting on an object.

Front

What is an example of balanced forces?

Back

An example of balanced forces is when two people push a stationary car with equal force in opposite directions, resulting in no movement.
