Which of the following is equation of motion?
- F=ma
- E=mc^2
- V= u + at
- P = VI
Explanation
The standard equations of motion for an object moving with uniform (constant) acceleration are
v = u + at
This is the first equation of motion, relating final velocity to initial velocity, acceleration, and time
s = ut + (1/2)at²
This is the second equation of motion, relating displacement to initial velocity, acceleration, and time
v² = u² + 2as
This is the third equation of motion, relating final velocity to initial velocity, acceleration, and displacement
Where:
v = final velocity
u = initial velocity
a = acceleration
t = time
s = displacement.
These equations are used in kinematics, which is the study of motion.
They are applicable when dealing with constant acceleration and motion in a straight line.
