1. Work & Power
1.1. Newton’s laws play a major role in mass and weight. Also mass and weight are important to know so we can always have exact measurements of things. They are both measured to give us the amount something ways or the measure of matter.
1.1.1. Work Power Work is referred to as the process of energy that is transferred to an object’s motion by applying force. It is generally represented as the product of displacement and force. Power is the amount of energy that is transferred in a unit of time. The SI unit of work is Joule (J) The SI unit of power is Watt (W) The formula for calculating the force is Work = Force * Displacement. The formula of calculating power is Power = Work/Time Work can be done in various other measures like kWh, MWh, GWh and volt (eV) Energy can be measured in units like GW, MW and kW. Work does not depend on time. Power depends on time.

2. Newton's Laws
2.1. Each law represents movement in some shape or form. Every single task you do has a reaction just like Newton's laws. Each law represents how an object will react or do something towards something else. Motion is all about the movement of objects, and the laws define what could/will happen to the object.
2.1.1. 1st Law
2.1.1.1. Inertia, an object resists a change in motion
2.1.2. 2nd Law
2.1.2.1. Acceleration of an object depends on the net force acting on the object, and the object’s mass. F= m x a
2.1.3. 3rd Law
2.1.3.1. For every action there is an equal and opposite reaction.
2.2. I CAN!!
2.2.1. I can design and conduct an investigation regarding Newton’s Second Law of Motion to show the relationship among force, mass and acceleration. (b)
2.2.2. I can explain how force, mass, and acceleration are related. (b)
2.2.3. I can state the direction of motion after the interaction of two objects. (b)
2.3. What do Newton’s 3 Laws of Motion explain?
