Forces and Motion

1 Speed

1.1 s=d/t

1.1.1 Speed=distance/time

1.2 Units

1.2.1 Speed m/s

1.2.2 Distance m

1.2.3 Time s

1.3 Amount of time taken for an object to cover a distance

1.3.1 How fast it is going

2 Weight

2.1 w=mg

2.1.1 Weight=mass x gravity

2.2 It is measured in Newtons (N)

2.2.1 It is the force of an object due to mass and the amount of gravity

3 Force

3.1 f=ma

3.1.1 Force=mass x acceleration

4 Terminal Velocity

4.1 Terminal Velocity is when an object falls at a constant velocity in a fluid as the forces acting on it are equal

5 Work Done

5.1 w=fd

5.1.1 Work= force x distance

5.2 The units are Joules (J)

5.3 Work done calcuates how much enegry is needed to push an object with a force, a distance

6 Newtons Laws

6.1 First Law

6.1.1 An object will continue to be either stationary or move in a straight line at constant speed, unless resultant force acting on it

6.2 Second Law

6.2.1 Force on object directly proportional to its mass times acceleration f=ma

6.3 Third Law

6.3.1 Every force applied to object surface there is opposite equal reaction force
