What is displacement?
The distance in a certain direction
What is a scalar force?
Quantity only has magnitude (size)
What is a vector force?
Has magnitude and direction
Give 3 examples of a scalar force?
Time, mass, distance
Give 3 examples of a vector force?
Weight, displacement, acceleration
What can a force do?
Change the shape of an object, change its state at rest or its motion
What is Newtons 3rd law? (Resultant force)
When 2 objects interact with each other, they exert equal and opposite forces on each other
What is Newtons 1st law?
If forces are acting on one another and are balanced it means the resultant force is 0, when moving it stays moving at a constant speed
What is a required to draw a resultant force diagram?
A parallelogram see iPad for more
