What else can I help you with?
Can a situation exist in which an object has zero acceleration and nonzero velocity even for an instant?
No, if an object has zero acceleration, its velocity cannot be changing. If the velocity is nonzero, it must either be increasing or decreasing, which requires acceleration.
What's the difference between instantaneous velocity and instantaneous acceleration?
Instantaneous velocity is the rate at which an object is moving in a uniform direction, distance per unit time, at any given instant in time. instantaneous acceleration is the rate at which an object's velocity is changing at any given instant in time
What will be instantaneous acceleration if average acceleration is zero?
If the average acceleration is zero, it means that the object's velocity is not changing over time. Since instantaneous acceleration is the acceleration at a specific moment in time, it can still have a non-zero value depending on the instantaneous velocity of the object at that moment.
Can an object have zero velocity and nonzero acceleration?
Yes, an object can have zero velocity and nonzero acceleration. This occurs when the object is changing its direction but not its speed. For example, in circular motion, the object's velocity is constantly changing direction, leading to a nonzero acceleration even when its speed is constant.
What is instentaneous acceleration?
Instantaneous acceleration is the rate of change of velocity at a specific moment in time. It indicates how quickly the velocity of an object is changing at that instant. It is typically calculated as the derivative of velocity with respect to time.
Is the rate at which an object changes velocity?
No, velocity is the instantaneous speed of an object, the rate of change would be the acceleration of the object.
If the instantaneous velocity of an object is constant then so is acceleration.?
the velocity increases at a constant rate
What is acceleration at instantaneous maximum velocity?
In the case of an object thrown, batted, teed off, or dropped, its acceleration at the instant of its maximum velocity is 9.8 meters per second2 downward.
What is the importance of uniform acceleration graph in physics what is instantaneous velocity?
Uniform acceleration graphs help visualize how an object's velocity changes over time. They show a constant rate of change in velocity, which can be used to calculate properties like displacement and time. Instantaneous velocity is the velocity of an object at a specific moment in time, representing the object's speed and direction at a given instant.
In physical science what are the 3 types of acceleration?
The three types of acceleration in physical science are constant acceleration, variable acceleration, and instantaneous acceleration. Constant acceleration is when an object changes its velocity at a steady rate, variable acceleration is when an object changes its velocity at different rates, and instantaneous acceleration is the acceleration of an object at a specific moment in time.
What does a tangent to a velocity-time graph measure?
It will measure acceleration in the direction towards or away from the origin.
Do you agree with the statement an object with a zero velocity can have an acceleration greater than zero do you agree?
Yes. If it weren't so, an object that isn't moving could never be made to move at all! Of course, once you apply acceleration (which implies a change of velocity), the object's velocity won't stay zero. But for a brief instant, the velocity can be zero while accelerating.
