Prof. Shiva Prasad, Department of Physics, IIT Bombay
Recapitulate
â€¢ We discussed the definition of
force in relativity.
â€¢ The acceleration, in general, is
not in the same direction as
force.
â€¢ We considered two special cases
when force and acceleration are
in the same direction.

Equations
We found an expression
relating a constant force and
the initial and final speed of
the particle after a given
time.

This equation can be
rewritten in a different
form to enable us to
calculate the speed after
a given time t, when a
particle is subjected to a
force F, in one
dimensional motion.
