The momentum of a body is defined as the product of is mas and velocity. Momentum = Mass x Velocity. If a body is at rest then obviously its velocity is zero. Therefore, its momentum also becomes zero.

Which has greater momentum an old school freight train at rest or a roller skate moving downhill?
The Roller-skate Momentum = (mass) multiplied by (speed) . Anything moving has more momentum than anything that's not moving. The thing that's not moving has zero speed, so it also has zero momentum.
How does launching your rocket relate to this law of motion?
If a rocket is at rest (zero momentum) in outer space, where there is no gravity, then as long as there are no Outside forces on it its momentum must always be zero (consevation of momentum). This must be true even if an internal explosion brakes it into pieces. The pieces must fly off in such a way that their net vector momentum is zero. Turning on the engine is like an internal explosion. The hot gasses, which have mass, are ejected out the back at high velocity so the gas has momentum. In order to keep the total momentum zero the rocket must move forward so its momentum just equals the backward momentum of the gasses and the net momentum of both is zero. The same is almost true when taking off from earth. Because of the Earth's gravity(outside force) the upward momentum of the rocket won't quite equal the downward momentum of the gasses but its almost the same.
Jim walewander slides into second base what happens t his momentum?
When Jim Walewander slides into second base, his momentum carries him forward towards the base. As he reaches the base, his momentum slows down and eventually stops, allowing him to come to a complete rest. The friction between his body and the ground helps to slow him down and maintain his balance during the slide.
Why does momentum have no designated SI unit name?
It does. Momentum=mass* velocity. Momentum is kilogram meters per second
When kinetic energy doubled what happens to momentum?
Momentum increases
Describe the momentum of objects at rest?
momentum is the tendency of an object to stay in motion or the force (energy) required to stop an objects motion. an object at rest (not moving) has no momentum.
How do you find momentum at rest?
Momentum is defined as the product of the mass and the velocity. P = mv. As the body is at rest its velocity v = 0. Hence momentum P =0.
What is the momentum of a resting particle?
Momentum = (mass) x (velocity)If the particle is at rest, velocity = 0, and momentum = 0.
What is the momentum of a 5000kg truck at a rest?
Zero.
Is the momentum of a 5000kg truck that is still standing is greater than the momentum of a 3000kg truck that is also at rest?
No.
Which has a greater momentum a heavy truck at rest or a moving skeatboard?
skateboard. momentum is mass times velocity thus if 0 velocity=0 momentum
What is a example of a momentum of zero?
An object at rest. Actually that's the only possible example for a single object. For two objects, you can have objects moving in opposite directions; for example, one may have a momentum of +100 units, and the other, a momentum of -100 units.
What is mometum?
momentum is an object's tendency to remain in motion, or to remain at rest. momentum can also be described as the product of the mass and velocity of an object. "an object at rest tends to stay at rest unless acted upon by an outside force"
Can a body at rest have acceleration?
No a boday while rest cannot be in acceleration because of the momentum of the body ...........................
How much momentum does an object at rest have?
NONE ! i don't think
Which has a greater momentum an automobile at rest or a moving skateboard?
skateboard
Which has more momentum a speeding baseball or an ocean liner at rest in the harbor?
Anything that's speeding, or in motion at all, has more momentum than anything else that's at rest. (Anywhere.)
