Why is it hard to stop fast moving cars?
It is hard to stop fast-moving cars because of their momentum. Momentum is the product of an object's mass and velocity, and the greater the momentum, the more force is required to change the object's speed or direction. Fast-moving cars have high momentum, making it difficult for brakes to overcome that momentum and bring the car to a stop quickly.
Explain why a fast moving freight train cannot be stopped quickly?
A fast moving freight train carries a lot of momentum due to its large mass and high velocity. Stopping it quickly would require overcoming this momentum, which would need a significant amount of force applied over a longer distance. Additionally, the braking systems on trains are designed to gradually slow down the train to prevent damage to the cargo, tracks, and passengers.
Why is it hard to stop an object that is moving very fast?
When an object is moving very fast, it has a lot of momentum, which is the product of its mass and velocity. Stopping this object requires applying a force in the opposite direction of its motion, which can be challenging due to the high momentum. Additionally, factors such as air resistance and friction can also contribute to the difficulty of stopping a fast-moving object.
What does Momentum do?
Momentum is basically the amount of force it takes to slow something down. Force is Mass times Acceleration, so weight and speed are a factor. A large object like a bus, moving at even a slow speed has a lot of momentum. It would take a lot of force to slow it down. A bullet would have a fair bit of momentum because of it's high speed, but not because of it's low weight. A bus traveling at the speed of a bullet would have a rediculous amount of momentum.

Why is it that an object with momentum is hard to stop?
An object with momentum is hard to stop because momentum is a measure of how much motion an object has. When an object is in motion, it has momentum, and stopping it requires applying a force in the opposite direction. The greater the momentum of an object, the more force is needed to bring it to a stop.

Two objects each have a mass of 70 kg what is their momentum?
Momentum is a measure of how hard it is going to be to get something to stop. Big objects going fast have lot of momentum. Getting hit by a truck will hurt more than getting hit by a fly. Momentum is worked out as mass x velocity so you need to know how fast it is going aswell as how much it weighs.
What pokeball do you need to catch raikou?
A master ball ,ultra ball or fast balls etc.NOTE:Raikou flees a lot
What quality of a bowling ball enables it to plow through a set of pins without slowing down?
The bowling ball does slow down. Momentum is conserved. It's just that it's a heavy ball so it has a lot of momentum, and the pins are light so overall the ball doesn't slow down enough for us to notice.

What is meant when someone says that an athletic team has a lot of momentum or less its momentum?
When a team has a lot of momentum, it means they are performing well and experiencing success, which can build confidence and motivation. When a team loses its momentum, it means they are facing setbacks or challenges that are hindering their performance and progress. Momentum is often used to describe the psychological and emotional state of a team in relation to their performance.
How does momentum a roller coaster?
A Lot
What is an example of low momentum?
Momentum = Mass x Velocity (p=mv)Of course an object at rest would have no momentum no matter what the mass is (velocity = 0 so momentum = 0).Playing volleyball with a balloon might be something that would be considered low momentum. You can hit it as hard as you like, but it has so little mass that its momentum can hardly overcome the air resistance.You might push a small car at, say 1/4 MPH, and it would have relatively little momentum.However a train traveling at the same 1/4 MPH would still have a lot of momentum.
Is a master ball the only way to catch Cresselia?
No! You can use a fast ball by folloing her, saving when you by her location then catching her with a fast ball! It is possible, why? Because if you use one at the very start of battle it is a lot stronger than a ultra ball and it has almost the same amount of strength as a master ball, I did it with 75% of the legendaries! Good luck!
How fast will a tennis ball loose its bounce?
It depends. A shot with backspin will drop a lot faster then a topspin or flat shot.
How did Led Zeppelin get themselves out there?
By playing in local venues a lot, being dedicated to their work, and getting the word about their new group as fast as possible. They were 'The Yardbirds' before so they already had momentum.
What should you upgrade for better gaming?
For high-end gaming you would need a fast processor (CPU) fast and a lot of RAM and a fast video card that includes a lot of built-on RAM.
