When can you accelerate even when your speed doesn't change?
"Acceleration" means a change of speed or direction of motion, or both.If you change direction ... like turning a corner ... then there is acceleration,even though your speed is constant.Anything traveling on a circular track, even at a constant speed, has constantacceleration.
What is uniform motion?
A ball rolling at a constant speed at the same rate of speed on a still surface.
Define non uniform motion?
Think of uniform as everything moving together. For example, in uniform circular motion describes the motion of a body traversing a circular path at constant speed. The distance of the body from the axis of rotation remains constant at all times. If the motion was non-uniform the distance of the body from the axis of rotation would vary.
How do you calculate brake pedal force and deceleration?
when breaks are applied for moving car whose velocity will be decreases and finally car will be at rest position acceleration = (final velocity - initial velocity)/time taken = (0-u)/t = -(u/t) negative acceleration is called deceleration deceleration = - acceleration chennakesavarao@itimes.com
When a car's velocity is positive and its acceleration is negative what is happening to the car's motion?
It is moving in the positive direction at a rate which is increasing.
The velocity of an object moving in a straight line changes at a constant rate when the object is experiencing constant?
acceleration
What is the acceleration of a car moving in a straight line at a constant rate of 29 meters per second for 4 seconds?
"Constant rate" implies there is no acceleration - acceleration is zero.
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".
Why an object moving in a circular path at a constant speed is undergoing acceleration and has a force excert on it?
-- An object with no net force on it continues moving at constant speed in a straight line.If it's not moving in a straight line, then there must be net force acting on it.-- "Acceleration" is the word for the situation where either speed or direction of motion changes.Even if speed is constant, acceleration is present if the direction is changing.
Does an object with a constant speed have an acceleration?
If it's moving in a curve or some other non-straight path, then yes. If it's moving in a straight line, then no.
What does mean the velocity remains constant?
there is no acceleration if the body is moving with constant velocity
How is am object moving at a constant speed and in a straight line like an object at rest?
An object moving at a constant speed in a straight line has an acceleration of 0. An object at rest also has an acceleration of 0. So, the two things I see in common are their accelerations, which are both 0.
What describes an object with constant velocity?
Constant speed, moving in a straight line, zero acceleration, zero net force acting on it.
Does a particle moving in a straight line have acceleration?
A particle moving in a straight line may or may not have acceleration. Acceleration is adifferent phenomenon altogether. the rate of change of velocity is acceleration, a particle can move in a straight line with a constant velocity thus having no acceleration & it can also move with increasing or decreasing velocities thereby accelerating or deaccelerating.
When velocity is positive and acceleration is zero what happens to an objects motion?
When acceleration is zero, then the object is moving in a straight line with constant speed. (That's the effective meaning of constant velocity.)
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.
What must you know about an object that is 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.
