newtons laws

Newtons’ first law

If the forces acting on an object are balanced, the resultant force on an object is zero.

resultant force

• Resultant force (single force acting on an object) : if the resultant force acting on an object isn’t zero then the object will move, accelerate or decelerate

• If the resultant force is zero rhen the object remains stationary

Balanced force

• all directions are equal and therefore the object stays in the middle

Newton’s second law

• formula: Force = Mass x acceleration or F=MA

• the more force on an object = the more acceleration applied

• Meanwhile if the object is heavier = the harder it is to speed up

Unbalanced force

• there is an uneven direction and the object will be pulled towards that uneven direction

Newton’s third law

When two objects interact with each other, they exert equal and opposite forces on each other

• in simple terms: the objects are the same size but they act in opposite directions

• For example: when you jump off a boat, you go forward but the boat moves backwards
