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.

How do you calculate the velocity of an object if you know its momentum and mass?

Back

Velocity can be calculated using the formula v = p/m, where p is momentum and m is mass.

Front

What is the unit of momentum?

Back

The unit of momentum is kg m/s.

If a 2 kg cart has a momentum of 16 kg m/s, what is its velocity?

Back

8 m/s.

How do you find the mass of an object if you know its momentum and velocity?

Back

Mass can be calculated using the formula m = p/v, where p is momentum and v is velocity.

What is the unit of mass?

Back

The unit of mass is kg.

How do you calculate weight from mass?

Back

Weight can be calculated using the formula W = mg, where W is weight, m is mass, and g is the acceleration due to gravity (approximately 9.81 m/s²).
