Net Force

Front

What is net force?

Back

Net force is the vector sum of all the forces acting on an object. It determines the object's acceleration and direction of motion.

Front

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

Back

To calculate net force when multiple forces are acting in the same direction, you add the magnitudes of the forces together.

Front

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

Back

To calculate net force when forces are acting in opposite directions, you subtract the smaller force from the larger force and take the direction of the larger force.

Front

What is the net force if two equal forces of 10N are acting in opposite directions?

Back

The net force is 0N, indicating that the forces are balanced.

Front

What is an unbalanced force?

Back

An unbalanced force occurs when the net force acting on an object is not zero, causing the object to accelerate in the direction of the net force.

Front

What is a balanced force?

Back

A balanced force occurs when the net force acting on an object is zero, resulting in no change in the object's motion.

Front

What role does gravity play in net force calculations?

Back

Gravity is a force that pulls objects towards the Earth, and it must be considered when calculating the net force acting on an object, especially when it is in free fall.

Front

If a car has a forward force of 54N and a backward force of 73N, what is the net force?

Back

The net force is 19N backwards.

Front

What is the unit of force?

Back

The unit of force is the Newton (N).

Front

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

Back

If the net force acting on an object is zero, the object will remain at rest or continue to move at a constant velocity.
