newtons laws

Newton’s First Law

Also called the Law of Inertia; it states that an object at rest stays at rest, and an object in motion stays in motion unless acted upon by an unbalanced force.

Inertia

The tendency of an object to resist changes in its motion.

Newton’s Second Law

Explains the relationship between force, mass, and acceleration using the formula F = m × a.

Force (F)

A push or pull acting on an object; calculated using mass times acceleration and measured in newtons (N).

MASS (m)

The amount of matter in an object; it affects how much force is needed to move the object

Acceleration (A)

The rate of change in velocity; increases with more force or decreases with more mass.

Newton’s third law

states that for every action there is an equal and opposite reaction

Action-Reaction Force Pair

Two forces that are equal in size and opposite in direction, acting on different objects.

unit of force

• The newtons named by Isaac newtons 1(N) = 1kg -(m s)

Law of action and reaction

• In Newton's Third Law, the forces have equal magnitude but opposite direction.
