The body is not zero, but the sum of all forces on it is. -- "Uniform velocity" means no acceleration. -- Acceleration is force/mass . -- If acceleration is zero, that's an indication that force must be 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.
Acceleration is the CHANGE in velocity; you're assuming CONSTANT velocity. So the acceleration is zero.
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.
No, a stationary object cannot have a non zero angular acceleration. Angular acceleration is a measure of how an object's angular velocity changes over time, so if an object is not rotating, its angular acceleration is zero.
If a train is stopped suddenly, its velocity will be zero since velocity is the rate of change of displacement over time. Acceleration is the rate of change of velocity over time, so the train's acceleration could be non-zero during the stopping process.
I am not sure what you mean by reversing a zero acceleration. An object's acceleration can, of course, change over time.
The acceleration of a pendulum at the mean position is zero because the force of gravity acting on the pendulum's mass is balanced by the tension in the string. When the pendulum is at its mean position, the forces acting on it are equal and opposite, resulting in a net force of zero and therefore zero acceleration.
Yes, it is possible to have zero acceleration with a non-zero velocity. This occurs when the velocity is constant. On a velocity-time graph, a flat, horizontal line represents constant velocity, while a zero slope (flat line) represents 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".
Acceleration is maximum at the extreme points of a simple pendulum because that is where the velocity is zero and the direction of acceleration changes from negative to positive (or vice versa). This change in acceleration direction leads to a maximum magnitude of acceleration at the extreme points.
The acceleration of a vehicle moving with uniform velocity is zero. This is because acceleration is the rate of change of velocity, and if the velocity is constant and not changing, then the acceleration is zero.
Constant speed. Zero acceleration.
When an objects net force is zero, its acceleration is zero. No force , no acceleration.
When acceleration is zero, the object's velocity can still be changing if the initial velocity is not zero. However, if acceleration is zero and the initial velocity is also zero, then the object's velocity will remain constant.
Suppose you accelerate in your car from stopped to 50 km.hr-1. When you were stopped your instantaneous speed was zero. At the end of the period of acceleration your instantaneous speed was 50 km.hr-1. If your rate of acceleration was constant then your average speed was 25 km.hr-1.
