They describe the motion of objects in terms of  their MASS and  the FORCES acting on them Mass – the amount of matter that an object contains a measure.

Forces. Force: A push or a pull on an object. A vector quantity. Two Types of Forces: Contact Forces: When the object is directly pushed or pulled. Field.

Notes Force. Force is a push or pull exerted on some object. Forces cause changes in velocity. The SI unit for force is the Newton. 1 Newton = 1 kg m/s.

Newton’s Laws of motion. Forces We have talked about different forces before but haven’t examined them in depth. A force is a push or a pull on an object.

4-4 Newton’s Second Law of Motion Newton’s second law is the relation between acceleration and force. Acceleration is proportional to force and inversely.

If the sum of all the forces acting on a moving object is zero, the object will (1) slow down and stop (2) change the direction of its motion (3) accelerate.

Force as a vector

Net force

The Maths in Physics isn’t bad. However you do need to know your trigonometry.

Lets look at an apple on a slope Assuming the apple is stationary. If the weight of the apple 100 grams. And the angle of the slope is 25 degrees. Find the friction force

Now Find the reaction force

Example: Q8 5.1

Is my answer correct below? If it is not explain why?

Newtons First Law  Lets think of some real life examples to try and explain this?  Groups of 3

Equilibrium Think about this? Does a body have to be at rest to be in equilibrium?
