Net Force - Flashcard

Front

What is the 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 acceleration.

Front

What is force?

Back

A force is a push or pull exerted on an object that can cause it to change its velocity.

Front

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

Back

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

Front

What happens when forces are balanced?

Back

When forces are balanced, the net force is zero, and the object remains at rest or continues to move at a constant velocity.

Front

What is an unbalanced force?

Back

An unbalanced force occurs when the total forces acting on an object are not equal, causing the object to accelerate in the direction of the net force.

Front

If a 10 N force is applied to the right and a 5 N force is applied to the left, what is the net force?

Back

The net force is 5 N to the right (10 N right - 5 N left = 5 N right).

Front

What is the unit of force?

Back

The unit of force is the Newton (N).

Front

What is the effect of net force on an object's motion?

Back

The net force determines how an object will move; it can cause an object to start moving, stop moving, or change direction.

Front

If two forces of 15 N and 20 N are acting in opposite directions, what is the net force?

Back

The net force is 5 N in the direction of the larger force (20 N - 15 N = 5 N).

Front

What is inertia?

Back

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