Acceleration

Acceleration is…

any change in velocity

Speeding up in the positive direction on a position v time graph…

the line goes up and gets steeper over time

Acceleration is…

any change in velocity

Speeding up in the positive direction on a position v time graph…

the line goes up and gets steeper over time

Slowing down in the positive direction on a position v time graph…

the line goes up and gets shallower over time

Speeding up in the negative direction on a position v time graph…

Line goes down and gets steeper over time

Slowing down in the negative direction on a position v time graph…

line goes down and gets shallower over time

Speeding up in the positive direction on a velocity v time graph…

above zero and goes away from zero

slowing down in the positive direction on a velocity v time graph…

above zero and goes towards zero

Speeding up in the negative direction on a velocity v time graph…

below zero and going farther from zero

slowing down in the negative direction on a velocity v time graph

below zero and going closer to zero

The SIGN(+ or -) of the slope on a velocity v time graph…

represents the direction of the acceleration.

Speeding up on a motion map in the positive direction…

vectors get longer going to the right

Slowing down on a motion map in the positive direction…

vectors get shorter going to the right

Speeding up on a motion map in the negative direction…

vectors get longer going to the left

Slowing down on a motion map in the negative direction…

vectors get shorter going to the left

Sign of the acceleration(← or →) when speeding up…

same as the direction of the motion

Sign of the acceleration(← or →) when slowing down…

opposite as the direction of motion

Units of acceleration are…

m/s/s or m/s²

formula for finding acceleration…

change in velocity /change in time(Vfinal-Vinital/change in time)
