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?
-2a
If a car moves at constant speed also moving at constant velocity give an example?
A car moving at constant speed in a straight line is also moving at constant velocity.
What do you mean by velocity?
As a moving object's velocity decreases its momentum decreases?
True
As a moving object's velocity decreases does its momentum decreases?
true

A car moving at constant speed in a straight line is also moving at constant velocity.
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.

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
What is uniform velocity and uniform accelration?
If a car moving in a straight line travels equal distance in equal time no matter how small these distances may be, the car is said to be moving with a CONSTANT or Uniform Velocity.
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).
