What is kinetic energy?

What is kinetic energy?

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

Can you give me an example of kinetic energy in real life?

Sure! A moving car has kinetic energy. The faster it goes, the more kinetic energy it has. For instance, a car traveling at 60 mph has significantly more kinetic energy than one at 30 mph.

How does kinetic energy relate to potential energy?

Kinetic energy and potential energy are both forms of mechanical energy. Potential energy is stored energy based on an object's position, while kinetic energy is the energy of motion. They can convert into each other, like a roller coaster at the top of a hill (potential) that speeds down (kinetic).

What factors affect kinetic energy?

Kinetic energy is affected by two main factors: the mass of the object and its velocity. Increasing either mass or velocity increases kinetic energy.

Is kinetic energy always positive?

Yes, kinetic energy is always a positive value because mass and the square of velocity are both positive. It cannot be negative.
