define acceleration derive an expression, relating acceleration , until velocity , final velocity , and time under which condition can the acceleration of a body zero
Answers
Explanation:
acceleration is the rate of change of the velocity of an object with respect to time. Accelerations are vector quantities (in that they have magnitude and direction). The orientation of an object's acceleration is given by the orientation of the net force acting on that object.
The longer the acceleration, the greater the change in velocity. Change in velocity is directly proportional to time when acceleration is constant. If velocity increases by a certain amount in a certain time, it should increase by twice that amount in twice the time.
Velocity is a physical vector quantity; both magnitude and direction are needed to define it. The scalar absolute value (magnitude) of velocity is called speed, being a coherent derived unit whose quantity is measured in the SI (metric system) as metres per second (m/s) or as the SI base unit of (m⋅s−1).
Final velocity (v) of an object equals initial velocity (u) of that object plus acceleration (a) of the object times the elapsed time (t) from u to v. v=u+at. Where: u = initial velocity. v = final velocity.
Acceleration of a moving body can be zero when the velocity of the body is constant (that is, does not change) as acceleration is the change in velocity
Answer:
ACCELERATION IS A SPEED DUE TO VELOCITY
IF F = MA
THEN MASS = F/M
