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 multiple forces are acting in the same direction?

Back

To calculate net force when multiple forces act in the same direction, you add their magnitudes together.

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

Back

To calculate net force when forces act in opposite directions, subtract the smaller force from the larger force and take the direction of 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

If a block is acted upon by a 10 N force to the right and a 5 N force to the left, what is the net force?

Back

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

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.

What is the relationship between net force and acceleration according to Newton's second law?

Back

According to Newton's second law, the net force acting on an object is equal to the mass of the object multiplied by its acceleration (F = ma).

What direction will an object move if the net force is directed to the left?

Back

If the net force is directed to the left, the object will accelerate and move to the left.

Front

How does friction affect net force?

Back

Friction opposes the motion of an object and reduces the net force acting on it.

Front

What is the effect of increasing mass on acceleration if the net force is constant?

Back

If the net force is constant and mass increases, the acceleration of the object will decrease.
