Momentum is mass times velocity, and it is a vector, so it has a direction.

This boulder has a momentum of 100*5=500 kgm/s in the direction of its motion.

Does a boulder rolling down a hill have momentum?

Yes, a boulder rolling down a hill has momentum because it is in motion and has mass. Momentum is the product of an object's mass and velocity, so the boulder possesses momentum as it moves.

What is the momentum of a 100 kilogram boulder rolling south downhill at a velocity of 5 meters per second?

The idea is to multiply the mass by the velocity.


Which has a greater momentum a car sitting still or a pebble rolling down a hill?

The pebble rolling down a hill has greater momentum because momentum is the product of mass and velocity. Even though the car has more mass, since it is stationary, its velocity is zero, resulting in zero momentum.


How do you calculate the momentum of a truck rolling down a hill?

You can calculate the momentum of a truck rolling down a hill by multiplying its mass by its velocity. Momentum = mass x velocity. Make sure to use consistent units for mass (kg) and velocity (m/s) in your calculation.


What is the momentum of an 8 kilogram bowling ball rolling a 2 meter per second?

momentum = mass x velocity 16 = 8 x velocity velocity = 2 m/s


What is the momentum of a 0.5 kg stone rolling at 4.0 minutes per second?

Momentum=mass*velocity 0.5*4=2kgms-1


Does gravity stop a ball from rolling?

No, gravity does not stop a ball from rolling. Gravity actually helps accelerate the ball as it rolls downhill by exerting a force on the ball in the direction of the slope. Friction between the ball and the surface it rolls on is what eventually slows it down and stops it.


Why is velocity needed to measure momentum?

In physics, the momentum of an object is the amount of energy it has moving in a direction. It is a product of its mass (weight) and its velocity (speed and direction) as in (momentum = Mass times velocity). Momentum changes when speed is increased or decreased, its direction changes, or its mass changes. An example of changing momentum is an object in space such as a meteor falling to the earth. Gravity can make it come down faster increasing its momentum. Atmospheric friction heats up the object causing some of it to burn away reducing its mass and decreasing its momentum. Another example of momentum is a snowball rolling down a snow covered mountain. Gravity pulling it down increases it speed (velocity) and momentum. Rolling down in snow, it accumulates snow, gets larger, increasing in weight (mass) and momentum.


As the speed of a rolling ball is increasing,the increasing speed is accompanied by?

momentum As the speed of a rolling ball is increasing, the increasing speed is accompanied by: a. increasing momentum.


If a ball is rolling of a velocity of 1.5 msec and has a momentum of 10.0 kg msec. what is the mass of the ball?

The momentum of an object is given by the product of its mass and velocity. In this case, the momentum is 10.0 kg m/s and the velocity is 1.5 m/s. Therefore, the mass of the ball can be calculated as 10.0 kg m/s / 1.5 m/s = 6.67 kg.
