Calculating 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

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

Back

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

Front

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

Back

To calculate net force when multiple forces are acting in opposite directions, you subtract the magnitude of the smaller force from the larger force and take the direction of the larger force.

Front

What is the unit of force in the International System of Units (SI)?

Back

The unit of force in the International System of Units (SI) is the Newton (N).

Front

If an object has a net force of 0N, what does that indicate about its motion?

Back

If an object has a net force of 0N, it indicates that the object is either at rest or moving at a constant velocity.

Front

What is the effect of a net force of 6N acting to the right on an object?

Back

A net force of 6N acting to the right will cause the object to accelerate to the right, according to Newton's second law of motion.

Front

What does it mean if the net force is 3N?

Back

A net force of 3N means that the object is experiencing a net acceleration in the direction of the net force, which is 3N.

Front

What is the relationship between net force and acceleration?

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).

Front

How can you determine the direction of net force?

Back

The direction of net force is determined by the direction of the greater force when forces are acting in opposite directions.

Front

What happens to an object if the net force acting on it is not zero?

Back

If the net force acting on an object is not zero, the object will accelerate in the direction of the net force.
