Newtons law of motion

Question 1

What is the three laws about?

Answer 1

These laws describe the relationship between the motion of an object and the forces acting on it.

Question 2

What is the first law?

Answer 2

Newton’s first law states that an object at rest will remain at rest, and an object in motion will continue in motion with a constant velocity in a straight line unless acted upon by an external force.
In other words, an object will not change its state of motion (either at rest or moving at a constant speed in a straight line) unless a force is applied to it.
This law is often summarised as “an object in motion stays in motion, and an object at rest stays at rest unless acted upon by an external force.”

Question 3

Second Law

Answer 3

Newton’s second law relates the force applied to an object, the mass of the object, and the resulting acceleration. It is often expressed as the formula F = ma, where:
* F represents the force applied to the object.
* m represents the mass of the object.
* a represents the acceleration of the object.
This law states that the force acting on an object is directly proportional to the product of its mass and acceleration. In simpler terms, the greater the force applied to an object, the greater the resulting acceleration, and the mass of the object determines how it responds to that force.

Question 4

Third Law

Answer 4

Newton’s third law states that for every action, there is an equal and opposite reaction. This law emphasises that when one object exerts a force on another object, the second object exerts an equal force in the opposite direction. These two forces are known as action and reaction pairs. This law is why, for example, when you push on a wall, the wall pushes back on you with an equal force in the opposite direction, preventing you from moving it.
