Which has a greater momentum a heavy truck at rest or a moving automobile?

The momentum of any object depends on its mass and its speed.
If a car and a bike are both moving at the same speed, then the car has
more momentum because it has more mass than the bike.
If the car and the bike are moving at different speeds, then we need to know
the speeds of each, in order to make any determination about their
respective momenta.

∙ 13y agoThe car has more momentum easily. It has the greater mass. The momentum equation is p=m x v
p= momentum
m= mass
v= velocity
ex.
So the bike weighs around 50 lbs and is going 20 mph
the car is about 1500 lbs and 20 mph
1500 x 20 = 30000
50 x 20 = 100

p = m * v
Momentum (p) is equal to the mass (m) of the object times its velocity (v). All in SI units.

∙ 11y agoThe momentum of the heavy truck at rest is zero and so is definitely less than a moving automobile no matter how lighter it is than the heavy truck and how fast it is going - as long as it is moving.

∙ 6y agoMomentum is given by mass x velocity. Thus we cannot be precise without the masses. To have equal momenta, the train would need a mass 2.5 times that of the car. As that is likely to be far too low a figure (just the locomotive is likely to be at least 50 times that of the car), the train would have more momentum.

∙ 9y agoMomentum is equal to mass multiplied by velocity, p = mv. Therefore, the greater momentum depends on the mass because you and your bike should have the same velocity. If you weigh more than your bike, you would have the greater momentum.

∙ 14y agogiven p = mv, where:
p = momentum
m = mass of the object
v = velocity
and on the assumption the bike weighs more than the car, the car will have greater momentum.

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
A piece of putty moving with 1 unit of momentum strikes to a heavy bowling ball that is initially at rest After the putty sticks to the ball both are set in motion with a combined momentum that is?

Why does a particle of lesser mass accelerate more quickly than a particle of greater mass?
the slower one has more energy because it does not use it all moving.
What would not help decrease the frictional force when moving a heavy object?
Going abroad without your passport
What does momentum not depend on?
Energy. Two objects with the same momentum can have different kinetic energy. Example - A 1 oz projectile at 1000 ft/s and a 10 oz projectile at 100 ft/s have the same momentum. The lighter projectile has 10 times as much kinetic energy as the heavy projectile. Example - A 1 oz projectile at 1000 ft/s and a 100 oz projectile at 100 ft/s have the same kinetic energy. The heavier projectile has 10 times as much momentum as the lighter projectile. Momentum = m*v. Energy = (m*v*v)/2.

Why it is hard to stop fast moving and heavy vehicles?
Momentum.
When a wrecking ball hits a wall it is not moving fast How can it have enough momentum to knock down a wall?
Momentum is a function of both mass and speed. The wrecking ball isn't moving very fast, but it is extremely heavy; that is where its momentum comes from.
Which has the greater mass a heavy truck at rest or a rolling skateboard which has greater momentum?
The truck has the most mass, but because it is at rest, the skateboard has the most momentum.
Why is it harder to stop a heavy football player than a lighter football player?
A heavy football player is harder to stop because it has a greater momentum. In physics, momentum is equal to the mass of an object times its velocity. If a 50 kilogram kid and a 70 kilogram man were running at the same speed, the man would be harder to stop because he would have a greater momentum.

Does an object have to be heavy in order to have momentum?
No. Even a single electron has momentum.

How can a heavy moving van have the same momentum as a small motorcycle?
Momentum = Mass x Velocity. They could have the same momentum if the motorcycle is going fast and the van is going slow. If the van weighs ten times as much as the motorcycle, and is driving 5 mph it would have the same momentum as the motorcycle driving 50 mph.
Does an object have to be heavy to have momentum?
no, it simply has to have mass.
How do you measure heavy objects such as automobile?
Pounds
Why does a golf ball make a bigger dent in the sand when dropped above the sand at higher heights?
It has more momentum from a higher height. Because momentum is always conserved, and momentum is the product of mass times velocity, more sand particles must move away faster in order to conserve the momentum of a heavy ball moving fast. The ball is moving faster from a higher height because the acceleration due to gravity (-9.81 m/s^2) increases the velocity of a falling object after each second its been falling.
