There are four basic equations of motion related to linear projection of an object.
There are a few terms that should be known before using these equations:
Time: t
Distance: s
Velocity: Rate of change of distance,
Initial velocity = u
Final velocity = v
Acceleration: Rate of change of velocity,
EQUATIONS OF MOTION:
i - Finding final velocity, given intial velocity, acceleration and time:
ii - Finding final velocity, given initial velocity, acceleration and distance:
iii - Finding distance given average velocity and time:
iv - Finding distance given initial velocity, time, and acceleration:
Special Case:
To find the distance given only velocities and acceleration, rearrange the equation no.2 as shown,
If the problem is related to free fall, initial velocity can be zero.
