What constant acceleration in SI units must a car have to go from zero to 61 in 12?
Acceleration is the change in velocity divided by change in time. The SI units for velocity and time are meters per second (m/s) and the second (s), respectively. Therefore, the SI unit of acceleration is meters per second per second (m/s^2). In this problem we have a car accelerating from 0 m/s to 61 m/s in 12 s. The acceleration is thus 61 m/s divided by 12 s to yield an answer of 5.1 m/s^2.

If a body is moving with constant velocity is it moving with constant acceleration?
An object moves with constant velocity when there is no net force acting upon it. If there are no forces acting on an object, or if the forces acting on it "cancel out" leaving a net force of zero acting on the object, it will have zero acceleration. With a zero acceleration, the velocity of the object will be constant.
Is your speed is constant if you are traveling in a straight line with an acceleration of zero?
If your acceleration is zero, then yes, you are traveling at a constant speed. The path does not matter. Acceleration measures the change in velocity, so an acceleration of zero means that there is zero change in velocity and therefore the speed is constant.
Why is acceleration zero when the body is moving with a constant velocity?
Acceleration is the CHANGE in velocity; you're assuming CONSTANT velocity. So the acceleration is zero.
Does an object experiencing a constant velocity have a zero or non-zero value for acceleration?
An object experiencing a constant velocity has zero acceleration. This is because acceleration is defined as the rate of change of velocity over time. When velocity is constant, there is no change in velocity, leading to zero acceleration.
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.
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".
When can you have no acceleration?
To make acceleration equal zero. The velocity must be constant. For example, if velocity is constant at 10 m/s^2 its acceleration is zero. The same is true if velocity is 0 m/s^2.
What is your acceleration if you have a constant velocity?
If your velocity is constant, then your acceleration is zero.
When the velocity of a particle is constant its acceleration is also constant?
When the velocity of a particle is constant, it means there is no change in speed or direction. Therefore, its acceleration is zero because acceleration is the rate of change of velocity. If the velocity is constant, there is no change to be measured, so the acceleration is constant at zero.
What must you know about an object Moving in a straight line to calculate its acceleration?
You must know its mass and the net force. If it is moving at constant velocity, the net force is zero and the acceleration is zero.
If an object is moving at a constant velocity what do you know about its acceleration?
"Acceleration" means change of velocity. If velocity is constant, then acceleration is zero.
If a body is moving with constant velocity is it moving with constant acceleration?
An object moves with constant velocity when there is no net force acting upon it. If there are no forces acting on an object, or if the forces acting on it "cancel out" leaving a net force of zero acting on the object, it will have zero acceleration. With a zero acceleration, the velocity of the object will be constant.
Is your speed is constant if you are traveling in a straight line with an acceleration of zero?
If your acceleration is zero, then yes, you are traveling at a constant speed. The path does not matter. Acceleration measures the change in velocity, so an acceleration of zero means that there is zero change in velocity and therefore the speed is constant.
Does a dish resting on a table have constant acceleration?
No, a dish resting on a table does not have constant acceleration. In fact, it has zero acceleration because it is not moving. Constant acceleration only occurs when an object's velocity changes at a constant rate over time.
What is acceleration of a rain drop that falls at a constant velocity?
If the velocity is constant then there is no acceleration. The acceleration is zero.
Why is acceleration zero when the body is moving with a constant velocity?
Acceleration is the CHANGE in velocity; you're assuming CONSTANT velocity. So the acceleration is zero.
Is it possible to achieve a constant acceleration?
Yes - for a while. Or indefinitely, if you will accept zero acceleration as "constant acceleration".
