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)
What is the gradient of acceleration time graph?
The gradient of an acceleration-time graph represents the rate at which the acceleration is changing over time. If the gradient is positive, it indicates an increase in acceleration, while a negative gradient indicates a decrease in acceleration. A horizontal line on the graph would represent a constant acceleration, where the gradient is zero.
What is the dimension of force if density and frequency and acceleration due to gravity are the bare quantities?
The dimension of force can be written using the Buckingham Pi Theorem as: force = density * frequency^2 * (acceleration due to gravity) This expression indicates that force has dimensions of mass per unit volume times inverse time squared, multiplied by acceleration due to gravity.
When will you say a body is in uniform acceleration and non-acceleration?
"Uniform acceleration" means that acceleration doesn't change over time - usually for a fairly short time that you are considering. This is the case, for example, when an object drops under Earth's gravity - and air resistance is insignificant. "Non-uniform acceleration", of course, means that acceleration does change over time.
What does a tangent to a velocity-time graph measure?
A tangent to a velocity-time graph represents the instantaneous acceleration of an object at that specific moment in time. It shows how the velocity is changing at that particular point.
