This is not generally correct.Selfphysicslearner said:
I see it must be actually:Vf=Vi+at then there is 2 Vi in formula which eliminates 1/2 multiplied makes itcnh1995 said:
Vf=at , this equation means final velocity = acceleration * time. This can happen only if initial velocity is 0, but in the equation Vi is the initial velocity and Vi is not 0 as per the equations wrriten.Selfphysicslearner said:
Velocity and acceleration are two fundamental concepts in physics that describe the motion of an object. Velocity refers to the rate of change of an object's position over time, while acceleration refers to the rate of change of an object's velocity over time. In other words, velocity measures how fast an object is moving, and acceleration measures how quickly its velocity is changing.
Velocity and acceleration are closely related in physics. Acceleration is the derivative of velocity, meaning it is the rate of change of velocity over time. This means that if an object's velocity is changing, it is experiencing acceleration. Conversely, if an object is experiencing acceleration, its velocity is changing.
Average velocity and acceleration refer to the overall change in an object's position or velocity over a given time interval. Instantaneous velocity and acceleration, on the other hand, refer to the specific velocity or acceleration of an object at a particular moment in time. Average values are calculated over a longer period, while instantaneous values are calculated at a specific point in time.
Velocity and acceleration play a crucial role in determining an object's motion. An object with a constant velocity will continue to move at the same speed and in the same direction, while an object with a changing velocity (i.e. acceleration) will experience a change in its motion. Acceleration can cause an object to speed up, slow down, or change direction.
Yes, the equations for velocity and acceleration can be applied to all types of motion, as long as the motion is in a straight line and the acceleration is constant. This includes both linear motion (straight line) and rotational motion (circular or curved path). However, for more complex motion, such as projectile motion, additional equations and principles may need to be applied.
