FLASHCARD QUESTION
Front
What is the formula for calculating kinetic energy?
Back
The formula for calculating kinetic energy (KE) is KE = 1/2 mv², where m is the mass of the object and v is its velocity.
3.
FLASHCARD QUESTION
Front
How does mass affect kinetic energy?
Back
Kinetic energy is directly proportional to the mass of the object; as the mass increases, the kinetic energy increases, assuming velocity remains constant.
4.
FLASHCARD QUESTION
Front
How does velocity affect kinetic energy?
Back
Kinetic energy is proportional to the square of the velocity; as the velocity increases, the kinetic energy increases exponentially.
5.
FLASHCARD QUESTION
Front
Calculate the kinetic energy of an object with a mass of 10 kg moving at 2 m/s.
Back
Using the formula KE = 1/2 mv², KE = 1/2 * 10 kg * (2 m/s)² = 20 J.

If a bicycle has a mass of 15 kg and is traveling at 4 m/s, what is its kinetic energy?
Back
The kinetic energy is 120 J, calculated using KE = 1/2 * 15 kg * (4 m/s)².
7.
FLASHCARD QUESTION
Front
What is the kinetic energy of a 2 kg ball moving at 3 m/s?
Back
The kinetic energy is 9 J, calculated using KE = 1/2 * 2 kg * (3 m/s)².
