Calculating 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.

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

Back

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

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

Back

To calculate net force when two forces are acting in opposite directions, you subtract the smaller force from the larger force.

What is the unit of force in the International System of Units (SI)?

Back

The unit of force in the SI system is the Newton (N).

Front

What is the effect of balanced forces on an object?

Back

Balanced forces do not change the motion of an object; the object remains at rest or continues to move at a constant velocity.

Front

What is the effect of unbalanced forces on an object?

Back

Unbalanced forces cause an object to accelerate, changing its velocity and direction.

If an object has a net force of 0 N, what can be said about the forces acting on it?

Back

If an object has a net force of 0 N, the forces acting on it are balanced.

What happens to the net force if two forces of equal magnitude act in opposite directions?

Back

If two forces of equal magnitude act in opposite directions, the net force is 0 N, resulting in balanced forces.
