What is the acceleration of vehicle moving with uniform velocity?
The acceleration of a vehicle moving with uniform velocity is zero. This is because acceleration is the rate of change of velocity, and if the velocity is constant and not changing, then the acceleration is zero.
What is the acceleration of a vehicle that goes from 70m s to a stop in 35s?
The acceleration of the vehicle can be calculated using the formula: acceleration = (final velocity - initial velocity) / time taken. Substituting the values, we get acceleration = (0 m/s - 70 m/s) / 35 s = -2 m/s^2. Thus, the acceleration of the vehicle is -2 m/s^2, in the opposite direction to its initial velocity.
What is the acceleration of a vehicle that changes its velocity from 80 km h to a dead stop in 13 s?
As velocity is reduced, acceleration is negative. Acceleration = change in velocity / time taken Velocity is m/second is got by multiplying 80 km p h by a fraction 5/18 which gives 200/9 m/s 200/9 is divided by 13s would give the required acceleration. That equals 1.7094 m/s2 So the retardation is 1.7094 m/s2
What is the acceleration of a vehicle that changes its velocity from 500 kmh to a dead stop in 20 s?
The acceleration of the vehicle can be calculated using the formula: acceleration = change in velocity / time. First convert the velocity from km/h to m/s (500 km/h = 138.89 m/s). The change in velocity is 138.89 m/s (final velocity) - 0 m/s (initial velocity) = 138.89 m/s. So, the acceleration is 138.89 m/s / 20 s = 6.9445 m/s^2.
What is the rate at which an object changes velocity is called?
It is acceleration. Recall the accelerator hold in case of two wheeler and accelerator pedal in case of four wheeler. After the engine is started then we turn the throttle and vehicle starts moving from rest and soon the velocity goes on increasing. The more we turn in case of two wheeler and the more we press the pedal in case of four wheeler, the speed gets increased so quickly. So 'rate of' phrase is used to mean any change with respect to time or change happening in one second. Rate of displacement is velocity Rate of change in velocity is acceleration Rate of doing work is power Rate of flow of charge is electric current.
When does one feel the effects of velocity in a moving vehicle when it is moving uniformly or when its motion changes?
One feels the effects of velocity in a moving vehicle when its motion changes, such as when the vehicle accelerates, decelerates, or changes direction. When a vehicle is moving uniformly, there are no noticeable changes in speed or direction, so the effects of velocity are not as perceptible.

The acceleration of a vehicle moving with uniform velocity is zero. This is because acceleration is the rate of change of velocity, and if the velocity is constant and not changing, then the acceleration is zero.

example of a change in acceleration while travelling at constant speed?
An example of a change in acceleration while traveling at constant speed can be observed when a vehicle moves in a circular path or takes a turn. Although the speed remains constant, the direction of the motion changes, which results in a change in velocity. Since acceleration is the rate of change of velocity, this alteration in direction causes a change in acceleration, even when the speed is constant.
What graph shows uniform acceleration of a moving vehicle?
A velocity-time graph would show uniform acceleration of a moving vehicle as a straight line with a constant positive slope, indicating that the vehicle is accelerating at a consistent rate.
How can you observe acceleration when you are in vehicle?
You can observe acceleration in a vehicle by feeling your body being pushed backwards when the vehicle accelerates, and pushed forwards when it decelerates. Additionally, you can observe the speedometer increasing as the vehicle accelerates, indicating a change in velocity.
At higher speeds a vehicle's rate of acceleration will be?
At higher speeds, a vehicle's rate of acceleration will typically decrease due to factors like air resistance and engine limitations. This means that it will take longer for the vehicle to increase its speed as it gets closer to its maximum velocity.
Which is also called as retardation or deceleration?
Braking is another term used for retardation or deceleration. It refers to the process of reducing the speed or velocity of an object or vehicle.
A car is moving at a constant speed is it accelerating?
This is one of those theoretical situations, like the frictionless surface you will see in physics problems. The short answer is that no, a car travelling at a constant speed is not accelerating. Acceleration is a change in velocity over time. Velocity is speed, so if you have zero change in velocity over a period of time, you have acceleration of zero. In the real world, you will have other factors acting on the vehicle, which would affect the acceleration.
