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 according to Newton's second law of motion.

Front

How do you calculate net force when multiple forces are acting on an object?

Back

To calculate net force, add all the forces acting in the same direction and subtract the forces acting in the opposite direction.

Front

What is a balanced force?

Back

Balanced forces are equal in size and opposite in direction, resulting in no change in motion of the object.

Front

What is an example of unbalanced forces?

Back

An example of unbalanced forces is when one force is greater than another, causing an object to accelerate in the direction of the greater force.

Front

What happens to an object at rest when balanced forces act on it?

Back

An object at rest will remain at rest when balanced forces act on it, according to Newton's first law of motion.

Front

What is the significance of the direction of forces in calculating net force?

Back

The direction of forces is crucial because forces acting in opposite directions will reduce the net force, while forces in the same direction will increase it.

Front

What is the net force on an object if two equal forces of 5 N act in opposite directions?

Back

The net force would be 0 N, as the forces cancel each other out.

Front

What is the net force on an object if a force of 10 N acts to the right and a force of 4 N acts to the left?

Back

The net force would be 6 N to the right (10 N - 4 N = 6 N).

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 mass of the object.

Front

How does mass affect the net force required to accelerate an object?

Back

According to Newton's second law, the greater the mass of an object, the greater the net force required to achieve the same acceleration.
