Front

What is Net Force?

Back

The total force acting on an object when all the individual forces are combined. It determines the object's motion.

Front

What is the formula for calculating Net Force?

Back

Net Force = Force applied by one object + Force applied by another object (in the same direction).

Front

What is the difference between Speed and Velocity?

Back

Speed is the distance traveled per unit of time without direction, while Velocity is speed with a specified direction.

Front

What is Potential Energy?

Back

The energy stored in an object due to its position or state. For example, a raised object has potential energy.

Front

What is Kinetic Energy?

Back

The energy an object possesses due to its motion. It depends on the mass and speed of the object.

Front

What is an Unbalanced Force?

Back

A force that causes an object to change its state of motion. It occurs when the total forces acting on an object are not equal.

Front

What is a Balanced Force?

Back

Forces that are equal in size but opposite in direction, resulting in no change in motion.

Front

What is Friction?

Back

A force that opposes the motion of an object. It occurs when two surfaces come into contact.

Front

What is the Law of Inertia?

Back

An object at rest will stay at rest, and an object in motion will stay in motion unless acted upon by an unbalanced force.

Front

What is Acceleration?

Back

The rate of change of velocity of an object. It can be caused by a change in speed or direction.
