Question

State the equations of motion of a free falling object from the equations of constant accelerated motion

Answer 1

Hey dear,

◆ Newton's kinematics eqns -
- Newton's kinematic equations are used to describe relationship between distance, time, velocity and acceleration.
- These are only applicable for uniformly accelerated motion.
- Standard kinematics equations
(1) v = u + at
(2) s = ut + 1/2 at^2
(3) v^2 = u^2 + 2as

◆ Kinematic equations for freely falling body-
Here,
Acceleration a = g
Displacement s = h,
Initial velocity u = 0

(1) First kinematics eqn -
v = gt
(2) Second kinematics eqn -
h = 1/2 gt^2
(3) Third kinematics eqn -
v^2 = 2gh

Hope this is helpful...
