Net Forces

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 an unbalanced force?

Back

An unbalanced force is a force that results in a change in the motion of an object, causing it to accelerate.

Front

What is a balanced force?

Back

A balanced force occurs when two or more forces acting on an object are equal in size and opposite in direction, resulting in no change in motion.

Front

What happens to an object when the net force acting on it is zero?

Back

When the net force acting on an object is zero, the object remains at rest or continues to move at a constant velocity.

Front

In which scenarios can you identify unbalanced forces?

Back

Unbalanced forces can be identified in scenarios where an object is accelerating, changing direction, or starting to move from rest.

Front

What is the significance of direction in net force calculations?

Back

The direction of the net force determines the direction of the object's acceleration and motion.

Front

How does friction affect net force?

Back

Friction is a force that opposes motion; it can reduce the net force acting on an object, affecting its acceleration.

Front

What is the role of mass in determining net force?

Back

Mass is a measure of an object's resistance to acceleration; according to Newton's second law, net force equals mass times acceleration (F=ma).
