Impulse-Momentum

Front

What is momentum?

Back

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

Front

How is momentum calculated?

Back

Momentum (p) is calculated using the formula: p = m × v, where m is the mass of the object and v is its 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.

Front

What is the unit of momentum?

Back

The unit of momentum is kilogram meter per second (kg m/s).

Front

If a biker has a mass of 75 kg and moves at 5 m/s, what is their momentum?

Back

375 kg m/s.

Front

How can two objects have the same momentum?

Back

Two objects can have the same momentum if they have different masses and speeds, such that their mass times velocity is equal.

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 does impulse relate to momentum?

Back

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

Front

What is the relationship between force, time, and momentum?

Back

The greater the force applied over a longer time, the greater the change in momentum.

Front

Which has more momentum: a bowling ball or a ping pong ball moving at the same speed?

Back

A bowling ball has more momentum because it has a greater mass.
