Net Force / KE.PE Review

Front

What is Net Force?

Back

Net Force is the total force acting on an object after all the individual forces are combined. It determines the object's motion.

Front

What is Kinetic Energy?

Back

Kinetic Energy is the energy an object possesses due to its motion, calculated using the formula KE = 1/2 mv², where m is mass and v is velocity.

Front

What is Potential Energy?

Back

Potential Energy is the stored energy of an object due to its position or state, commonly associated with height in a gravitational field.

Front

How does height affect Potential Energy?

Back

As an object is lifted higher, its Potential Energy increases due to the greater gravitational force acting on it.

Front

What is the relationship between Kinetic Energy and speed?

Back

Kinetic Energy increases with the square of the speed; if speed doubles, Kinetic Energy increases by a factor of four.

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 happens to an object's motion when unbalanced forces act on it?

Back

An object will accelerate in the direction of the net force when unbalanced forces act on it.

Front

What is the formula for calculating Kinetic Energy?

Back

KE = 1/2 mv², where m is mass and v is velocity.

Front

What is the formula for calculating Potential Energy?

Back

PE = mgh, where m is mass, g is the acceleration due to gravity, and h is height.

Front

What is an example of an object with Kinetic Energy?

Back

A tennis ball rolling across the court is an example of an object with Kinetic Energy.
