What else can I help you with?
When does an object have no acceleration?
When it is stationary, or when the velocity is constant. If it is speeding up or slowing down, it has acceleration.
For an object that is speeding up at constant rate how would the acceleration vs time graph look?
A line angled upward
What is the angular acceleration of the minute hand of a clock?
The hands of a clock move at a constant speed, not slowing or speeding up. Therefore, the acceleration is a constant 0 rad/s2
What is aceleration velocity?
Acceleration is the rate of change of velocity. It can be positive (speeding up), negative (slowing down), or zero (constant speed). Velocity is the rate of change of an object's position with respect to time.
Is constant acceleration same as constant speed?
no because constant acceleration describes and object speeding up at an equal rate wheras constant speed describes an object travelling at the same speed over time. By the way i h8 physics don't ever do it
Is it possible when a body to have acceleration when moving constant speed?
Yes. "Acceleration" does not mean "speeding up". It means any change in speedor direction of motion. If the body is moving on a curve, even at a constant speed,its direction is changing, so there is acceleration.
The velocity of a body was noted to be constant during five minutes of its motion What was its acceleration during this interval?
The acceleration of the body was zero during this interval because its velocity was constant. Acceleration is the rate of change of velocity, so if the velocity does not change, the acceleration is zero.
What does a positive acceleration position-time graph indicate about the motion of an object?
A positive acceleration position-time graph indicates that the object is speeding up or moving in the positive direction.
Can it be possible that a particle have constant speed must have zero acceleration?
It's possible, but not necessary, that a particle moving with constant speedhas zero acceleration. In order for acceleration to be zero, it's also necessarythat the particle be moving in a straight line.An object moving with constant speed around a curve has acceleration."Acceleration" does not mean "speeding up".
What are Statements about acceleration?
Acceleration is the rate of change of velocity with respect to time. Acceleration can be positive (speeding up), negative (slowing down), or zero (constant velocity). Acceleration is a vector quantity, meaning it has both magnitude and direction.
Can an object accelerate and have a constant speed at the same time?
No, an object cannot accelerate and have a constant speed at the same time. Acceleration is a change in velocity, which includes speed or direction. If an object has a constant speed, it means there is no acceleration occurring.
What are three facts about acceleration?
Acceleration is the rate of change of velocity with respect to time. Acceleration can be positive (speeding up), negative (slowing down), or zero (constant velocity). Acceleration is a vector quantity, meaning it has both magnitude and direction.
