FLASHCARD QUESTION

Front

What is momentum?

Back

Momentum is the product of an object's mass and its velocity, represented by the formula p = mv.

2.

FLASHCARD QUESTION

Front

How does mass affect momentum?

Back

An object with greater mass will have more momentum at the same velocity compared to an object with less mass.

3.

FLASHCARD QUESTION

Front

What is the law of conservation of momentum?

Back

The total momentum of a closed system remains constant if no external forces act on it.

4.

FLASHCARD QUESTION

Front

What is Kepler's first law of planetary motion?

Back

Planets orbit the sun in elliptical orbits, with the sun located at one focus.

5.

FLASHCARD QUESTION

Front

What happens to the momentum of a moving object when it collides with a stationary object?

Back

The total momentum before and after the collision remains constant.

6.

FLASHCARD QUESTION

Front

What is kinetic energy?

Back

Kinetic energy is the energy of an object due to its motion, calculated using the formula KE = 1/2 mv².

7.

FLASHCARD QUESTION

Front

How does velocity affect kinetic energy?

Back

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