Net Force Practice

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 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 0 N, what does that indicate about its motion?

Back

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

Front

What is the direction of net force if two equal forces act in opposite directions?

Back

If two equal forces act in opposite directions, the net force is 0 N, meaning there is no net direction.

Front

What happens to an object's motion if a net force is applied?

Back

If a net force is applied to an object, it will accelerate in the direction of the net force according to Newton's second law of motion.

Front

What is Newton's second law of motion?

Back

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

Front

How does mass affect the acceleration of an object when a net force is applied?

Back

The greater the mass of an object, the less acceleration it will experience for a given net force, according to the formula F = ma.

Front

What is the significance of the direction of net force?

Back

The direction of net force determines the direction in which an object will accelerate.
