Net Force Review

Front

What is net force?

Back

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

Front

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

Back

When forces are acting in the same direction, you add their magnitudes to find the net force.

Front

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

Back

When forces are acting in opposite directions, you subtract the smaller force from the larger force to find the net force.

Front

What does it mean if the net force on an object is zero?

Back

If the net force is zero, the object is in a state of equilibrium, meaning it is either at rest or moving at a constant velocity.

Front

What is the significance of balanced forces?

Back

Balanced forces result in a net force of zero, meaning there is no change in the object's motion.

Front

What happens to an object when an unbalanced force acts on it?

Back

An unbalanced force causes the object to accelerate in the direction of the net force.

Front

Can net force be negative?

Back

Net force itself is a vector quantity and can have a negative value depending on the direction of the forces involved.

Front

If two people push a boy with equal force in opposite directions, what is the net force on the boy?

Back

The net force on the boy is zero, as the forces cancel each other out.

Front

What is the relationship between mass and acceleration in Newton's second law?

Back

According to Newton's second law, the acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass (F=ma).

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.
