Theory about uniformly accelerated motion

Answer 1

From a kinematic perspective, just observing the motion of an object, we can say that an object is experiencing uniform acceleration if the magnitude of the object's velocity changes at a constant rate but maintains the same direction.

From a dynamic perspective, as a consequence of Newton's second law, we know that whenever the net force on an object is constant (in magnitude and direction) the object will undergo uniform acceleration.

Answer 2

When an object undergoes one-dimensional uniformly accelerated motion, its instantaneous velocity increases linearly with time. If it is assumed that the initial velocity of the object is zero at time t = 0, then its instantaneous velocity v at any later time t is given by

v = at (1)

where a is the acceleration, which is constant in magnitude and direction.

Answer 3

3. if a body starts from rest and moves with uniform acceleration = V=

1. if a body starts from rest and moves with uniform acceleration = V=at

2. if a body starts from rest and moves with uniform acceleration = d=1/2 at2

3. if a body starts from rest and moves with uniform acceleration = V2=2ad

Answer 4

Galileo's Law of Uniformly Accelerated Motion simply states that the speed of a body would increase proportionally with the length of time that it moved. It also says that the distance of an object fell or rolled would increase proportionally with the square of the time that it moved.

Answer 5

A body is in uniform acceleration when its acceleration is increasing at a constant rate.
