PS unit 1

newtons first law, inertia, and motion

Distance How far you traveled between two positions. It it always positive. It is a scalar quanity
Displacement change in position. It is the straight line distance between your starting position and ending position. It is equal to Final position minus initial position. It can be positive or negative. It is a vector quanity
scalar quantity that only requires magnitude (how big)
vector quantity that requires both magnitude (how big) and directions
speed how fast your going
velocity speed times distance
Newton's First Law AKA the law of inertia. An object will stay at rest and a object will stay in motion in the same direction until acted upon by an unbalanced force
Mass a measure of the amount of matter an object contains. Also, a measure of the amount of inertia an object has
Inertia the resistance an object has to changes in its motion
Force any push or pull (interaction) that can cause a change in motion
