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

What does it mean for forces to be unbalanced?

Back

Unbalanced forces occur when the total force acting on an object is not zero, resulting in a change in the object's motion.

Front

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

Back

To calculate net force in the same direction, sum all the forces together.

Front

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

Back

To calculate net force in opposite directions, subtract the smaller force from the larger force.

Front

What is the effect of an unbalanced force on an object at rest?

Back

An unbalanced force will cause an object at rest to start moving in the direction of the net force.

Front

What happens to the speed of an object if the net force acting on it is in the opposite direction of its motion?

Back

The speed of the object will decrease.

Front

What is the significance of friction in net force calculations?

Back

Friction is a force that opposes motion; it must be considered when calculating net force to determine the actual force acting on an object.

Front

In a frictionless environment, what can be said about the motion of an object?

Back

In a frictionless environment, an object will continue to move at a constant velocity unless acted upon by an unbalanced force.

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

What is an example of a scenario with unbalanced forces?

Back

A scenario where a person pushes a stationary box, causing it to move, is an example of unbalanced forces.
