Who has greater momentum an 18-wheeler parked at the curb or a volkswagen rolling down a hill?

Momentum = mass * velocityTherefore the Volswagen rolling down the hill has greater momentum than the truck which is sationary.Volkswagen: momentum = mass * velocityTruck: momentum = mass * 0 = 0


What are some examples of momentum?

Momentum is speed or force of movement and it is defined as moving body. Momentum must have both mass and velocity. Examples of momentum include if a car and big truck are rolling down a hill, the truck will roll faster. A bullet has a lot of momentum with a small mass.


Does a boulder rolling down a hill have momentum?

Yes, a boulder rolling down a hill has mass and velocity. Therefore, it has momentum because p = mv (momentum = mass x velocity).


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

Momentum is the product of mass x velocity. At zero velocity, momentum will also be zero.


Does gravity stop a ball from rolling?

Momentum is the product of mass and velocity. When an object slows down, the object reduces in velocity. Since Mass is constant, when velocity reduces momentum reduces. thus momentum can be what stops a rolling object. However, a resistive force the reason for the reduction of velocity and subsequently halting.


What is the difference between positive and negative momentum?

The difference between positive and negative momentum is the direction that the object is going. Left and down are negative, right and up are positive. For example: if a ball is rolling to the left, it has a negative momentum.


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.


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

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.

What is a sentence for embankment?

It was terrifying to watch the huge truck slide on the slippery road and go rolling down the steep embankment.


What is the force acting on 2800 kg truck if its slows down from 60 meter per secs. to 35 meter per secs. in 6 seconds?

(-)11,666.67 N. To calculate this, you need to use the impulse-momentum principle, whereby the change in momentum is equal to the force multiplied by the time over which the force is applied. The change in momentum here is the final speed x the mass - the initial speed x the mass. Then divide the answer by the time (six seconds) and the answer will be the force applied (in this case the answer is negative as the force is applied in the direction opposite to the direction of the truck's motion.)
