What is the law of motions?

Forces are pushes and pulls that act on objects and cause them to move or change shape. The Law of Motion states that every object in motion will remain in motion unless an external force acts on it. Newton's three laws of motion are the foundation of classical mechanics, which is the study of motion.

Newton's First Law of Motion: Objects at rest stay at rest and objects in motion stay in motion with the same speed and in the same direction unless acted upon by an unbalanced force. Newton's Second Law of Motion: The acceleration of an object is dependent upon two variables - the net force acting upon the object and the mass of the object. Newton's Third Law of Motion: For every action there is an equal and opposite reaction.

Newton's Third Law of Motion states that for every action, there is an equal and opposite reaction. It takes a force of 4.45 Newtons to move a kilogram of mass one meter per second squared. The force of friction is affected by surface area. The larger the surface area, the greater the friction.

Question: What are the three laws of motion? Clues: • Motion is the change in an object's position over time. • Isaac Newton wrote the laws of motion. • The three laws of motion describe how objects move. In pairs: Select and solve one of the tasks: A. Work in pairs to create a drawing that explains the three laws of motion. B. Write a song about the three laws of motion.

What is the first law of motion?
• An object at rest tends to stay at rest and an object in motion tends to stay in motion
• Force equals mass times acceleration

What is inertia?
• The tendency for objects to resist change in their state of motion
• The force that one surface exerts on another when the two surfaces rub against each other
• The force that opposes motion between two surfaces that are touching each other
