Impulse-Momentum

Front

What is impulse?

Back

Impulse is the change in momentum of an object when a force is applied over a period of time. It is calculated as the product of the average force and the time duration over which the force acts.

Front

What is momentum?

Back

Momentum is the product of an object's mass and its velocity. It is a vector quantity, meaning it has both magnitude and direction.

Front

How does momentum change when a force is applied?

Back

When a force is applied to an object, it causes a change in momentum. The change in momentum is equal to the impulse applied to the object.

Front

What is the formula for calculating momentum?

Back

The formula for momentum (p) is p = m * v, where m is mass and v is velocity.

Front

What happens to momentum when the speed of an object is doubled?

Back

When the speed of an object is doubled, its momentum also doubles, since momentum is directly proportional to velocity.

Front

What is the relationship between impulse and momentum?

Back

Impulse is equal to the change in momentum of an object. Mathematically, Impulse = Δp = p_final - p_initial.

Front

If an object is at rest, what is its momentum?

Back

If an object is at rest, its momentum is 0 kg m/s, since momentum is the product of mass and velocity (p = m * 0).

Front

What is the unit of impulse?

Back

The unit of impulse is Newton-seconds (N⋅s) or kg m/s.

Front

How do you calculate impulse?

Back

Impulse can be calculated using the formula Impulse = Force × Time (J = F × t).

Front

What is the effect of a larger mass on momentum?

Back

A larger mass results in greater momentum for the same velocity, as momentum is directly proportional to mass.
