Forces (Newton's Laws of Motion)

When Forces are balanced (Newton 1st Law)

an object at rest will remain at rest

E.g: Book Resting on a table

an object in motion will continue in motion at constant speed in a straight line in the absence of a resultant force acting on it.

Terminal Velocity, For Falling Object, when Weight = Air Resistance, No Resultant Force -> No Acceleration -> Falling at a constant velocity (Terminal Velocity), Factors Affecting Terminal Velocity, Mass The greater the mass, the greater the terminal velocity, Surface Area The greater the surface area, the smaller the terminal velocity

When Forces are UN-Balanced (Newton 2nd Law)

Newton’s second law of motion states that the resultant force acting upon an object is equal to the product of the mass and the acceleration of the object.

Fr = ma

Resultant of Parallel Forces

Resultant of Non-Parallel Forces (use vector diagram)

Newton 3rd Law

Newton’s third law of motion states that for every action there is an equal and opposite reaction If object A exerts a force on object B, then B exerts an equal but opposite force on A

Newton’s third laws tells us 4 characteristics of forces: 1. Forces always occur in pair. Each pair is made of an action and reaction. 2. Action and reaction forces are equal in magnitude. 3. Action and reaction forces are opposite in direction. 4. Action and reaction forces act on different bodies.

Scale Diagram to solve for forces

Use to solve

Resultant Forces Use Parallelogram/Triangle Method Resultant force must have double arrow head

Forces in Equilibrium ( No balanced forces) Use closed triangle method

Things to include in diagram: 1. Scale (1 cm rep 100N) 2. Parallelogram/ Triangle Method 3. Answer must include: Magnitude of Force and direction (means angle to which force)
