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.

Front

What happens to an object when the net force is zero?

Back

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

Front

What is the unit of force?

Back

The unit of force is the Newton (N).

Front

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

Back

To calculate net force, subtract the smaller force from the larger force and indicate the direction of the larger force.

Front

What is the effect of balanced forces on an object?

Back

Balanced forces do not change the motion of an object; it either remains at rest or moves with constant velocity.

Front

What is the direction of motion if the net force is directed to the left?

Back

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

Front

What is an example of unbalanced forces?

Back

An example of unbalanced forces is when one team pulls with a force of 100 N to the right and another team pulls with 50 N to the left, resulting in a net force of 50 N to the right.

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 object's mass.

Front

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

Back

According to Newton's second law, force equals mass times acceleration (F = ma). This means that for a given force, an increase in mass will result in a decrease in acceleration.

Front

What is the difference between mass and weight?

Back

Mass is the amount of matter in an object, measured in kilograms (kg), while weight is the force exerted by gravity on that mass, measured in Newtons (N).
