Newton’s Laws Poster
Teach kids how things move around us. A fun illustrated poster of Newton’s Laws of Motion explained by Isaac Newton himself!
Every science student has probably heard of Sir Isaac Newton. But not all science students know that he came up with the groundbreaking three laws of motion. This Newton’s laws poster shows the three laws of motion as formulated by Sir Isaac Newton. Students who want to understand how everyday phenomena happen, such as a rolling ball coming to a stop when it hits a wall. Even today, Newton’s laws continue to be significant and have helped scientists and engineers design bridges, create seat belts and airbags, and build spacecraft.

WHO WAS SIR ISAAC NEWTON?
Sir Isaac Newton is recognized as one of the greatest scientists and mathematicians of all time. His ideas were revolutionary and ultimately became the foundation of modern physics.
Born in Lincolnshire, England in 1642, he made significant contributions to the fields of mathematics, physics, astronomy, optics, and even theology. In 1686, he published a book where he presented his three laws of motion and revolutionized science. With his work, he was able to explain not just how things worked on Earth, but also in outer space. His ideas have influenced even modern inventions such as the airplane and space flight and helped us understand planetary motions.
WHAT ARE NEWTON’S THREE LAWS OF MOTION? Newton’s First Law: the law of inertia
The first law states that an object at rest will remain at rest or an object in motion will continue to move at a constant speed and in a straight line unless acted upon by an outside force.
In other words, things cannot start or stop moving unless a force is applied to them. The tendency of an object in motion to remain in motion is usually referred to as inertia.
A practical application of this law is seen when a driver suddenly hits the brakes of a car. The driver jerks forward because his body resists the change from the car’s continuous movement to a sudden stop.
Newton’s Second Law: the law of force
The second law is a formula (F = ma) that explains that the force acting on an object is equal to the product of that object’s mass and acceleration. This law describes how much an object will accelerate when a specific amount of force is applied to it.
To illustrate this, imagine you kick a ball. The force you give to the kick has a direct relationship to the ball’s acceleration, meaning that the harder you kick the ball, the faster or farther it moves.
Newton’s Third Law: the law of action and reaction
The third law states that for every action, there is an equal or opposite reaction. This means that forces come in pairs and that when an object exerts force on another object, that object exerts an equal and opposite force to the first object.
For example, a man sitting down on a chair exerts force on the chair equal to his weight. According to the third law, the chair also exerts an equal and upward force to the man to prevent the chair from collapsing.
