Calculating Net Force using Diagrams

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 act in the same direction, you simply 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 forces act in opposite directions, 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 SI system is the Newton (N).

Front

What does a free-body diagram represent?

Back

A free-body diagram represents all the forces acting on a single object, showing their direction and magnitude.

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.

Front

If an object has a net force of 0 N, what can be said about its motion?

Back

If the net force is 0 N, the object is either at rest or moving at a constant velocity.

Front

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

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 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, as acceleration is inversely proportional to mass.

Front

What is the effect of balanced forces on an object?

Back

Balanced forces result in no change in the object's motion; the object remains at rest or continues to move at a constant velocity.
