Net Force

Front

What is a balanced force?

Back

A balanced force occurs when two forces acting on an object are equal in size and opposite in direction, resulting in a net force of zero. The object remains at rest or continues to move at a constant velocity.

Front

What happens when forces are unbalanced?

Back

When forces are unbalanced, the object will accelerate in the direction of the larger force, causing a change in its motion.

Front

Define net force.

Back

Net force is the vector sum of all the forces acting on an object. It determines the object's acceleration according to Newton's second law of motion.

Front

If an object has a net force of 3 N to the right, what does this indicate?

Back

This indicates that the total force acting on the object is 3 Newtons directed to the right, which will cause the object to accelerate in that direction.

Front

What is the difference between balanced and unbalanced forces?

Back

Balanced forces result in no change in motion (net force = 0), while unbalanced forces cause an object to accelerate in the direction of the net force.

Front

What is an example of balanced forces?

Back

An example of balanced forces is a book resting on a table. The force of gravity pulling the book down is balanced by the normal force of the table pushing it up.

Front

What is an example of unbalanced forces?

Back

An example of unbalanced forces is pushing a shopping cart. If you push harder than the friction opposing the motion, the cart will accelerate in the direction you are pushing.

Front

What is the unit of force?

Back

The unit of force is the Newton (N).

Front

How do you calculate net force?

Back

To calculate net force, add all the forces acting on an object, taking into account their direction. Forces in the same direction are added, while forces in opposite directions are subtracted.

Front

What is inertia?

Back

Inertia is the tendency of an object to resist changes in its state of motion. An object at rest stays at rest, and an object in motion stays in motion unless acted upon by an unbalanced force.
