Why does a fast moving car have more momentum than a slow moving car?
A fast-moving car has more momentum than a slow-moving car because momentum is directly proportional to an object's velocity. The momentum of an object is the product of its mass and velocity, so the faster the object is moving, the greater its momentum.
If a car moves at constant speed also moving at constant velocity give an example?
An example of a car moving at constant speed and constant velocity would be a car driving along a straight road with no change in direction, where the speedometer shows a steady reading, and there are no changes in velocity or direction of motion. This means the car is moving at a consistent speed in a straight line without any acceleration or deceleration.
In what directions are positive velocity's?
Positive velocity can be in any direction as long as the object is moving in that direction. For example, a car moving northward has a positive velocity in the north direction.
When A car moving east with a velocity of 2m s is represented by a Which of the following represents the velocity of the car moving 4m s west?
The velocity of the car moving 4 m/s west would be represented by -4 m/s since motion in the opposite direction is indicated by a negative sign.
When a car's velocity is negative and its acceleration is positive what is happening to the car's motion?
The car is slowing down
Why is it that their is an acceleration when a car is moving?
There is only acceleration if the car's velocity changes. If it moves at a constant velocity, then there is no acceleration.

As a moving object's velocity decreases its momentum decreases.?
True

If you were standing in an enclosed car moving at constant velocity would you have to lean in some special way to compensate for the car's motion?
No, if the car is moving at a constant velocity, there is no need to lean in any special way to compensate for its motion. Your body is also moving at the same constant velocity as the car, so you will not feel any effect of the motion.
How does air cause a pressure against a car windscreen?
When a car is moving, this creates a difference in the relative velocity of the car as compared to the surrounding air. This creates a wind that presses on the windscreen. It doesn't actually matter, in terms of the amount of pressure, whether the car is not moving and the air is moving, or the car is moving and the air is not moving, what matters is only the difference in velocity between the car and the air.

What can be inferred about the velocity of a car that is moving with a constant momentum?
The velocity of the car is staying constant speed the whole time. It is not rising or diminishing at all.
Can a car moving at a constant velocity have acceleration at the same time?
No. Definitely not
How do you get the velocity of a grape?
it depends on the situation the grape is in! Velocity is the change in distance / change in time... for example: if a car moves 3 meters in 1 second. the car has a velocity of 3 m/s... or 6 meters in 2 seconds.. its velocity is still 3m/s velocity is a vector quantity however so you must be careful while solving velocity related problems... basically this means that velocity is also measured by which direction the object is moving.... if the car from the previous example is moving to the right, its velocity would be +3m/s.... if it were moving to the left it would be -3m/s. (moving left or right is all relative to the starting position of the car).
