Impulse-Momentum

Front

What is the Impulse-Momentum Theorem?

Back

The Impulse-Momentum Theorem states that the impulse on an object is equal to the change in its momentum.

Front

What is impulse?

Back

Impulse is the product of the average force applied to an object and the time duration over which it is applied.

Front

How is momentum defined?

Back

Momentum is defined as the product of an object's mass and its velocity.

Front

What are the units of momentum?

Back

The units of momentum are kg·m/s (kilogram meter per second).

Front

What is the relationship between impulse and momentum?

Back

Impulse is equal to the change in momentum of an object.

Front

What factors affect the momentum of an object?

Back

The momentum of an object is affected by its mass and velocity.

Front

How do you calculate impulse?

Back

Impulse can be calculated using the formula: Impulse = Force × Time.

Front

What happens to momentum in a closed system?

Back

In a closed system, the total momentum before an event is equal to the total momentum after the event (conservation of momentum).

Front

What is the formula for momentum?

Back

The formula for momentum (p) is p = mass (m) × velocity (v).

Front

What is the effect of increasing the time duration of a force applied to an object?

Back

Increasing the time duration of a force applied to an object increases the impulse, which in turn increases the change in momentum.
