What quantity is represented by the slope of a velocity time graph?
The slope of a velocity-time graph represents acceleration. It quantifies the rate of change of velocity over time, indicating how quickly an object's speed is increasing or decreasing. A positive slope indicates acceleration, while a negative slope indicates deceleration. If the slope is constant, the acceleration is uniform.
What is instantaneous velocity in math?
if under uniform acceleration or deceleration v = u + (a*t) where: v = instantaneous velocity u = initial velocity a = acceleration (negative if decelerating) t = time elapsed
What is the equation for uniform velocity?
V = constant Speed = constant Direction = constant Acceleration = 0
What will be acceleration of a car moving in a circular motion with constant speed.?
If body is moving in a circle with uniform or constant speed its acceleration will be uniform as velocity i.e. to say direction is changing at every point.
How does constant velocity differ from constant acceleration?
Constant velocity is a measure of distance traveled per unit of time at a uniform speed, such as miles per hour or feet per second. Constant acceleration is a measure of a continuing increase in velocity per unit of time, as when a car speeds up from 30 miles per hour to 40 miles per hour in 5 seconds, then from 40 miles per hour to 50 miles per hour during the next 5 seconds. It will then have had a constant acceleration of 10 miles per hour per 5 seconds.
What is the difference between increasing velocity and uniform velocity?
Increasing velocity means that the body is accelerating and a force is acting on the body to produce the acceleration. Uniform velocity means that there is no acceleration or deceleration and so no force acts on the body. (Note that in practice we cannot achieve perpetual motion because of either the decelerating force of gravity or friction).
How far does a plane fly in 15 seconds while it's velocity is increasing from 75 m s to 145 m s at a uniform rate of acceleration?
To calculate the distance traveled while the velocity is increasing, you can use the formula: distance = initial velocity * time + 0.5 * acceleration * time^2. In this case, the initial velocity is 75 m/s, the final velocity is 145 m/s, the acceleration is constant, and the time is 15 seconds. Plugging these values into the formula will give you the distance the plane travels during the acceleration period.
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.
When body have 2ms accleration in 15 seconds with a velocity 30ms does the velocity of the car uniform?
Although the question is stated in a somewhat confusing way, we can state withconfidence that the velocity of the car is NOT uniform, because a value is given forits acceleration. 'Uniform' motion means zero acceleration.
How far does a plane fly in 15 seconds while its velocity is increasing from 75 miles per second to 145 miles per second at a uniform rate of acceleration?
To find the distance traveled, we can use the formula: distance = initial velocity * time + 0.5 * acceleration * time^2. The initial velocity is 75 miles per second, the final velocity is 145 miles per second, and the time is 15 seconds. The acceleration can be found using the formula: acceleration = (final velocity - initial velocity) / time. Plug in the values to find the acceleration and then calculate the distance traveled in 15 seconds.
What is the difference between uniform and variable velocity?
Uniform velocity is constant speed in a straight line, while variable velocity changes in speed or direction over time. Uniform velocity has no acceleration, whereas variable velocity may have acceleration due to changes in speed or direction.
If a body is moving with a uniform velocity.what will be its acceleration?
If a body is moving with a uniform velocity, its acceleration will be zero. Acceleration is the rate of change of velocity, so if the velocity is constant, there is no change in velocity over time and thus zero acceleration.
Can uniform angular velocity has acceleration?
No, uniform angular velocity implies that an object is moving in a circle at a constant rate. Since acceleration is defined as any change in velocity (either speed or direction), if the angular velocity is constant, there is no acceleration present.
Why is acceleration zero with uniform velocity?
Uniform velocity means the velocity is not changing. Acceleration is defined as the rate of change of velocity. If velocity isn't changing, the rate of change is zero.
What is the acceleratipn of a body with uniform velocity and why?
The acceleration of a body with uniform velocity is zero because acceleration is the rate of change of velocity. If the velocity is constant, then there is no change in velocity over time, so the acceleration is zero.
How do you find the uniform acceleration if the speed and acceleration are given?
Find out the time using speed and acceleration, (time=speed/acceleration) and then use it to find out uniform velocity. From that find out uniform acceleration. (as uniform acceleration is equal changes of velocity over equal intervals of time)
Why is the body moving with a uniform velocity is zero?
The body is not zero, but the sum of all forces on it is. -- "Uniform velocity" means no acceleration. -- Acceleration is force/mass . -- If acceleration is zero, that's an indication that force must be zero.
