- He developed his three laws in order to explain why the orbits of the planets are ellipses rather than circles, at which he succeeded, but it turned out that he explained
What are the laws of motion ?
well to begin, there are 3
laws of motion. They all focus on
the motion of an object and forces
and forces acting on it.
Today, we're just going
to focus on the third law.
Which talks about ... Could
you guess ?
Newton's third law states that
when two bodies interact, they apply
forces to one another that are equal
in magnitude and opposite in direction.
Actions and Reactions!!!
In a rocket engine, hot exhaust gas is produced
through the combustion of a fuel with an oxidizer.
The hot gas flows through the rocket nozzle and
is accelerated to the rear of the rocket,
In re-action, a thrusting force is produced on the
The thrust accelerates the rocket as described
by Newton's 2nd law,but we're not gonna get into that.
For every action, there is
an equal but opposite reaction.
Motion is mathematically described
in terms of displacement, velocity,
acceleration, speed, and time.
Newton's third law is useful for
which forces are external to a system.
