FLASHCARD QUESTION

Front

What is Kinetic Energy?

Back

Kinetic Energy is the energy an object possesses due to its motion. It is calculated using the formula KE = 0.5 x mass x velocity².

2.

FLASHCARD QUESTION

Front

What is the formula for calculating Kinetic Energy?

Back

KE = 0.5 x m x v², where m is mass and v is velocity.

3.

FLASHCARD QUESTION

Front

If a 90 kg man is traveling at 25 km/h, how do you calculate his Kinetic Energy?

Back

Use the formula KE = 0.5 x 90 kg x (25 km/h)².

4.

FLASHCARD QUESTION

Front

What happens to Kinetic Energy if the velocity of an object is doubled?

Back

The Kinetic Energy quadruples (increases by a factor of 4) because KE is proportional to the square of the velocity.

5.

FLASHCARD QUESTION

Front

Calculate the Kinetic Energy of a 11 kg baby crawling at 2 m/s.

Back

KE = 0.5 x 11 kg x (2 m/s)² = 22 J.

6.

FLASHCARD QUESTION

Front

What is the unit of Kinetic Energy?

Back

The unit of Kinetic Energy is Joules (J).

7.

FLASHCARD QUESTION

Front

How does mass affect Kinetic Energy?

Back

Kinetic Energy increases with an increase in mass; if mass increases, Kinetic Energy increases.
