Any object with mass can be accelerated to a higher velocity, no matter what its current velocity is. All that is required is a force to further propel the object. For example, if a train (mass = 100 tons) moving at 100 miles per hour was hit from behind by a car (moving 200 miles per hour; mass = 1 ton), the train's resulting speed from the collision would be higher than its original 100 miles per hour. The very heavy train would, indeed, accelerate.

Why does a slow-moving loaded truck and a speeding rifle bullet each have a large momentum?
Both the loaded truck and the rifle bullet have large momentum because momentum depends on both mass and velocity. Even though the truck is moving slowly but has a large mass, and the rifle bullet is moving very fast with a relatively small mass, both contribute to their large momentum values.
Does high velocity affect rate of change of velocity?
Yes, high velocity can affect the rate of change of velocity. If an object is already moving at a high velocity, it may require more time or force to change its velocity compared to an object moving at a lower velocity due to inertia.
Can hail shatter a window?
Yes, hail can shatter a window if it is large and moving at a high velocity. The impact of large hailstones can cause glass to break, especially if the window is already weak or damaged.
Where is the most kinetic energy?
The most kinetic energy is typically found in moving objects that have a high velocity and a large mass. For example, a speeding car on a highway or a fast-moving bullet fired from a gun would have a significant amount of kinetic energy due to their velocity and mass.
When could a small object have the same momentum as a large object?
Yes. Momentum is based on mass and velocity, not physical size. 1 kg of styrofoam moving at 100 m/s has the same momentum as 1 kg of gold moving at 100 m/s, but the piece of styrofoam will be over 1000 times the size. Additionally, since the formula for momentum is mass times velocity, a 10 kg piece of gold moving at 10 m/s has the same momentum as a 1 kg piece of gold moving at 100 m/s. They both have a momentum of 100 kg-m/s.
Which moving object in all likelihood will have the greatest momentum?
A freight train traveling at high speed will have the greatest momentum, as momentum is directly proportional to both an object's mass and its velocity. The large mass of the train combined with its high velocity results in a significant amount of momentum.
Why does a slow moving train have a large momentum?
A slow-moving train has a large momentum because momentum is determined by both the mass and velocity of an object. Even though the train may be slow, its large mass contributes to a significant momentum. Momentum is a vector quantity that accounts for both the object's mass and its motion.
What is the difference between a small momentum and a large momentum?
The larger the momentum, the harder it will be to stop it. Thus, the larger the force needed to decelarate the object. Since momentum is directly proportional to the velocity, the larger the momentum, the larger the velocity.
How do you apply the concept of momentum to compare the mass and velocity of a slow moving train and of a high-speed bullet?
The momentum of an object is the product of its mass and velocity. In the case of a slow moving train and a high-speed bullet, the bullet would have a higher momentum due to its higher velocity even if its mass is smaller. This is because momentum is more affected by velocity than by mass.
Why do most rivers that have a large sediment load also have high water velocity?
Most rivers with a large sediment load also have high water velocity because faster-moving water has greater energy, allowing it to transport more sediment. Increased velocity helps lift and carry heavier particles, preventing them from settling. Additionally, steeper gradients and turbulent flow often characterize such rivers, further enhancing their ability to erode and transport sediments. This dynamic relationship between water velocity and sediment load is crucial for shaping river landscapes.
Why can't you feel the speedy movement of the earth as it travels around the sun?
The acceleration and deceleration of Earth is too gradual to feel. We normally do not perceive high velocity as long as the ride is smooth and the velocity is constant. What we feel are abrupt changes in the acceleration rate. I have heard that some skyscrapers have high-speed elevators that many times don't feel like their moving because they don't bump around and they accelerate and decelerate very smoothly.
In order for a small object to have a large momentun the object needs to be stationary true or false?
False. Momentum is a product of an object's mass and velocity, so even if the object is small, it can have a large momentum if it has a high velocity. It doesn't need to be stationary to have a large momentum.
