when a car travels equal distance in equal intervals of time its velocity is uniform and equal
Its value grows to become precisely equal to double its initial value, while its direction remains unchanged.
In free fall, when the air resistance is equal to the weight of the falling object, we say that the object has reached ________ velocity.
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.
When something increases in velocity, its momentum would increase because momentum is equal to its mass * velocity. This means that the momentum and velocity are proportional, so twice the velocity is twice the momentum, and so on.
Momentum is equal to the product of mass and velocity, so if the mass is equal, the one with greater velocity has greater momentum.
The velocity of the car in this case is changing (to specify velocity, you indicate a speed and a direction), therefore the car is accelerating.The velocity of the car in this case is changing (to specify velocity, you indicate a speed and a direction), therefore the car is accelerating.The velocity of the car in this case is changing (to specify velocity, you indicate a speed and a direction), therefore the car is accelerating.The velocity of the car in this case is changing (to specify velocity, you indicate a speed and a direction), therefore the car is accelerating.
The velocity of the body is constant if it covers equal displacements in equal intervals of time. This is because velocity is defined as the rate of change of displacement with respect to time. If the body is covering equal distances at equal intervals, then the velocity remains constant.
Mainly, when the velocity doesn't change. Also, in the case of varying velocity, the instantaneous velocity might, for a brief instant, be equal to the average velocity.
For the instantaneous value of average velocity, average speed and average velocity are equal.
Then you can say that the object's speed and the magnitude of its velocity are constant, and the magnitude of its acceleration is zero.
1. force that moves a car forward is the friction force between the tires and the road (ignoring what is going on mechanically in the car) 2. if the car is travelling at constant velocity, net force is zero - forces pushing car forward are equal to forces pushing car back
An object's average velocity is equal to its instantaneous velocity when the object is moving at a constant speed in a straight line. This means that the object covers equal distances in equal intervals of time, resulting in the average velocity over a period of time being equal to the instantaneous velocity at any given moment within that period.
