Question

explain all about
1.initial displacement
2.initial velocity
3.acceleration

Answer 1

A displacement is a vector whose length is the shortest distance from the initial to the final position of a point P. It quantifies both the distance and direction of an imaginary motion along a straight line from the initial position to the final position of the point.

acceleration
the rate of change of velocity per unit of time.


initial velocity

Initial Velocity Formula. Velocity is the rate that the position of an object changes relative to time. Forces acting on an object cause it to accelerate. This acceleration changes the velocity. The initial velocity,vi is the velocity of the object before acceleration causes a change.

Answer 2

1.If an object moves relative to a reference frame—for example, if a professor moves to the right relative to a whiteboard, or a passenger moves toward the rear of an airplane—then the object’s position changes. This change in position is known as displacement. The word displacement implies that an object has moved, or has been displaced.

Displacement is defined to be the change in position of an object.

2.Initial Velocity Formula

Velocity is the rate that the position of an object changes relative to time. Forces acting on an object cause it to accelerate. This acceleration changes the velocity. The initial velocity,vi is the velocity of the object before acceleration causes a change. After accelerating for some amount of time, the new velocity is the final velocity, vf.

3.In physics, acceleration is the rate of change of velocity of an object with respect to time. An object's acceleration is the net result of all forces acting on the object, as described by Newton's Second Law. The SI unit for acceleration is metre per second squared
