FLASHCARD QUESTION

Front

What is the formula for calculating kinetic energy?

Back

The formula for kinetic energy (KE) is KE = 1/2 mv², where m is the mass and v is the velocity.

2.

FLASHCARD QUESTION

Front

What is the kinetic energy of an object with a mass of 2 kg moving at a speed of 3 m/s?

Back

The kinetic energy is 9 J (KE = 1/2 * 2 kg * (3 m/s)²).

3.

FLASHCARD QUESTION

Front

What is the definition of potential energy?

Back

Potential energy is the energy stored in an object due to its position or configuration.

4.

FLASHCARD QUESTION

Front

What is the formula for calculating gravitational potential energy?

Back

The formula for gravitational potential energy (PE) is PE = mgh, where m is mass, g is the acceleration due to gravity, and h is height.

5.

FLASHCARD QUESTION

Front

How does height affect potential energy?

Back

Potential energy increases with height; the higher an object is, the more potential energy it has.

6.

FLASHCARD QUESTION

Front

What is the potential energy of a 5 kg object at a height of 10 m?

Back

The potential energy is 490 J (PE = 5 kg * 9.8 m/s² * 10 m).

7.

FLASHCARD QUESTION

Front

What is the relationship between kinetic energy and velocity?

Back

Kinetic energy is proportional to the square of the velocity; if velocity doubles, kinetic energy increases by a factor of four.
