F=m x a

What is a scalar quantaty
Unit(value)
What is a vector quantaty
Unit plus direction
What does the arrow do in a vector quantity
Shows which direction the force is acting in.
If the resultant Force is zero what is the effect
Speed stays the same remains constant
What is the effect if the resultant force doesn’t equal to 0
Acceleration -gets faster or deceleration -gets slower or changes direction
What is the lubricant in terms of friction
Anything that slows down the amount of friction for example oil
What is deformation
Changing shape due to a force
What is compression
Force changing or pushing together which changes the shape of an object.
What is tension
Force extending or pulling apart
What do an elastic limit
When the material no longer returns back to original form so not showing elastic behaviour
What does a Lever and pivot do to a force
It magnifies i
What is a moment
A turning force i.e. turning the handle
What is the equation for moments
Moment force x distance from pivot
