Physics Homework Guide on The Three Laws of Motion

If you are a student in a physics-related class, you must have encountered Newton’s three laws of motion scientific information. The law is common with a wide application in science-related disciplines. The law came into existence after its discovery by the famous Isaac newton.

If you intend to join any physics career, understand Newton’s three laws of motion worksheet.

The laws are basic and necessary for any physic class. Physics is a practice subject that draws its explanation and concepts from nature. To explain some of the natural phenomena or events, you need to make good use of Newton’s three laws of motion.

Here are is an explanation to help you understand the laws of motion

Newton’s first law of motion

Every physic tutor knows this law of motion very well. It describes how the body remains in its state of motion or rests in a straight line unless you subject it to any other external force. According to this law of motion, the body in a movement will remain in its motion state unless you compel it to stop by applying other external forces. A stationary body will remain in its stationary position until you subject it to other external forces.

A good example to explain the law Is a tiny moving car with a giraffe on top. The car will continue in its motion state until a different force, such as a wall, comes in to make it stop. The giraffe will continue moving because nothing makes it stop. The car completely stops after receiving a force from a wall.

Newton’s second law of motion (F = ma)

Newton’s second law of motion relates the mass (M)of an object, its acceleration (a), and the force (F).

When you apply a constant force on an object with mass, it begins to change in velocity (movement speed) or start accelerating. If there is a constant force on a body in motion, it will either increase its speed or reduce or change in direction.

High force = high acceleration + high mass

Low force = low acceleration + low mass

Low force = low acceleration + high mass

High force = high acceleration + low mass

Which is the best example of Newton’s second law of motion? An accident of moving a car pushed from the back is a good example to explain this law. When a fast-moving track hits a small car moving in the same direction from the back, it leads to a change in direction, making the car get out of the road.

Third law of motion

you can use the Newton’s third law of motion to explain the relationship between action and reaction force. According to the law, every action force results in a reaction force. It means that a force applied in one direction leads to the exertion of an equal force in the opposite direction.

When jumping, a force that makes you go up is exerted downwards in equal measure. Normally you and the ground are pushing one another.

Another good example of the third law of motion is swimming. When you kick your legs, you apply some force to the water. Water applies the same force to you, making it possible to move in a straight line. Water moves in the opposite direction in the form of ripples.


You cannot make it in a physics class without mastering Newton’s three laws of motion. They are the back-born of all other concepts your meet during your studies. If you are planning to join a physics-related career, start learning this law of motion. You will apply them as you continue with your career. Find more information of the three laws and deepen your understanding.
