Real life examples of the Three Laws of Motion

3 Laws of motion
in this video, I cover real-life examples of the three laws of motion.
Law 1 or the law of Inertia—states that matter wants to resist any change in motion
The speed or motion of an object will not change unless an outside force acts on it.
For example, this bowling ball would travel in straight line forever, but the friction of the floor, and air, plus the pins are outside forces and change the velocity of the bowling ball.
Astronauts appear to float in space because there is very little gravity pulling down on them So when they change their velocity upward the force of gravity is not pulling down on them and they can float.

If you are driving a car and it hits another car, the car stops but the people inside keep moving forward.
The outside force has acted on the car and not the person in the car. This is the same way a catapult works. The lever stops but the object keeps moving.

Law 2 of Motion

Newton’s 2nd Law: “The acceleration of an object depends on the force acting on it_ and the mass of the object

There is an equation associated with this law:

F= ma
Force = mass multiplied by acceleration

Think of shopping for groceries. The mass of an empty shopping cart is less than a full shopping cart so takes much less force to push the empty cart compared to pushing a cart that is filled up with stuff

Law Three

Newton’s 3rd Law of Motion --“For every action, there is an equal and opposite reaction

As the boy jumps down on the trampoline the trampoline pushes back in the opposite direction and causes the boy to go in the opposite direction.

As the balloon hits the ground the ground pushes back in an opposite direction which causes the balloon to change direction and move in the opposite direction.
