Net Force Review

Front

What is the net force?

Back

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

Front

What happens when forces are balanced?

Back

When forces are balanced, the net force is 0 N, and the object remains at rest or continues to move at a constant velocity.

Front

What is an unbalanced force?

Back

An unbalanced force occurs when the net force acting on an object is not zero, causing the object to accelerate in the direction of the net force.

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 directions.

Front

If a soccer ball is kicked with a force of 50 N to the left and another force of 30 N to the right, what is the net force?

Back

The net force is 20 N to the left (50 N left - 30 N right = 20 N left).

Front

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

Back

If the net force is to the right, the object will accelerate and move 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 net force?

Back

The greater the mass of an object, the greater the net force needed to accelerate it (Newton's second law: F = ma).

Front

What is the effect of friction on net force?

Back

Friction opposes motion, reducing the net force acting on an object and affecting its acceleration.

Front

If an object is moving at a constant speed, what can be said about the net force?

Back

If an object is moving at a constant speed, the net force acting on it is zero, indicating balanced forces.
