If an object has a mass of 10 kg and is moving at a speed of 5 m/s, what is its momentum?

Back

50 kg·m/s (calculated as momentum = mass × velocity).

How does the momentum of an object change if its speed doubles?

Back

The momentum doubles, since momentum is directly proportional to velocity.

In a closed system, if one object gains momentum, what happens to another object’s momentum?

Back

Another object must lose an equal amount of momentum to keep the total momentum constant.

Front

What is the relationship between mass and momentum?

Back

Momentum increases with an increase in mass, assuming velocity remains constant.

Why is it harder to stop a large truck compared to a small car?

Back

The large truck has a greater mass, resulting in greater momentum, making it harder to stop.

If a cat and a dump truck are both moving at the same speed, which has greater momentum?

Back

The dump truck has greater momentum due to its larger mass.
