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.
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.

The idea is to multiply the mass by the velocity.
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.
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.
momentum = mass x velocity 16 = 8 x velocity velocity = 2 m/s
Momentum=mass*velocity 0.5*4=2kgms-1
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.
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.
momentum As the speed of a rolling ball is increasing, the increasing speed is accompanied by: a. increasing momentum.
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.
