GEN SCI (translational motion)

translational motion

occurs when an object moves from one position to another

speed

distance/time unit: m/s

displacement

△x = xf - xi unit:m

velocity

vf = xi + at unit:m/s

average velocity

vave = △x ÷ △t unit: m/s

average acceleration

aave = △v ÷ △t

aave = v – v₀

           ——–

            v – t₀ unit:m/s*2

force

F= ma. unit:N

speed

The distance traveled by an object per unit of time. It tells us how fast an object moves.

displacement

The change in an object's position from its starting point to its ending point, including direction.

velocity

The rate of change of displacement over time. It tells us how fast an object moves and in what direction.

angular velocity

The rate at which an object rotates through an angle over time. It tells us how fast an object spins.

angular accelaration

The rate at which angular velocity changes over time. It tells us how quickly an object's rotation speeds up or slows down.
