You use the definition of acceleration as the rate of change of the velocity:a = dv/dt
In other words, you basically divide the change of velocity by the time - for a small time interval.
Acceleration = (speed at the end of some time interval minus speed at the beginning of the interval)/(length of the time interval)
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".
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.
By convention, yes, but the acceleration is negative
-- 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.
Acceleration = Final velocity - Initial velocity / time
Acceleration = (speed at the end of some time interval minus speed at the beginning of the interval)/(length of the time interval)
Change in velocity over the change in time
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.
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.
The only thing that causes or influences acceleration of an object is force.
If a body is moving at constant velocity in a straight line, the acceleration is zero and the net force acting on it is zero. F = ma F = m x 0 F = 0

"Constant rate" implies there is no acceleration - acceleration is zero.
