Momentum and Impulse Conceptual Questions

Front

What is impulse?

Back

Impulse is the change in momentum of an object when a force is applied over a period of time, calculated as Impulse = Force × Time.

Front

How is impulse related to momentum?

Back

Impulse is equal to the change in momentum of an object, expressed as Impulse = Δp (where Δp is the change in momentum).

Front

What is the formula for calculating momentum?

Back

Momentum (p) is calculated using the formula p = mv, where m is mass and v is velocity.

Front

What happens to momentum in a closed system?

Back

In a closed system, the total momentum remains constant if no external forces act on it.

Front

What is the unit of impulse?

Back

The unit of impulse is the newton-second (N·s), which is equivalent to kg·m/s.

Front

How does increasing force affect impulse?

Back

Increasing the force applied to an object increases the impulse, assuming the time duration remains constant.

Front

How does increasing time affect impulse?

Back

Increasing the time duration over which a force is applied increases the impulse, assuming the force remains constant.

Front

What is the relationship between impulse and force?

Back

Impulse is directly proportional to the average force applied and the time duration of that force.

Front

What is the significance of momentum in sports?

Back

Momentum is crucial in sports as it affects an athlete's ability to control their movements and maximize performance.

Front

What is the principle of conservation of momentum?

Back

The principle states that in the absence of external forces, the total momentum of a system remains constant.
