Net Forces

Front

What is net force?

Back

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

Front

How do you calculate net force?

Back

Net force is calculated by adding 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 happens when the net force on an object is zero?

Back

When the net force is zero, the object is in a state of equilibrium, meaning it will either remain at rest or continue to move at a constant velocity.

Front

What is the unit of force?

Back

The unit of force is the Newton (N).

Front

If a force of 10 N right and a force of 4 N left are acting on an object, what is the net force?

Back

The net force is 6 N right (10 N right - 4 N left = 6 N right).

Front

What is the effect of a net force on an object?

Back

A net force causes an object to accelerate in the direction of the net force according to Newton's second law of motion.

Front

What is inertia?

Back

Inertia is the tendency of an object to resist changes in its state of motion. It is directly related to the mass of the object.

Front

How does mass affect net force and acceleration?

Back

According to Newton's second law, the greater the mass of an object, the more force is required to achieve the same acceleration.

Front

What is the relationship between net force and acceleration?

Back

The relationship is described by Newton's second law: F = ma, where F is net force, m is mass, and a is acceleration.

Front

If a skateboarder pushes with a force of 25 N and the wind pushes back with 8 N, what is the net force?

Back

The net force is 17 N forward (25 N - 8 N = 17 N).
