Describe the motion that is occurring in each of these graphs. Ce) position E'j position time time Ce) (ed position position time time constant velocity = uniform motion April 17, 202 (acceleration = 0) m/" 1 Mot changing velocity = non-uniform or accelerated motion (acceleration F 0) A curved line on a position-time graph means that we have accelerated motion. A B C time time time position is changing! the accelerated motion whiform motion , slope is same Cearned live, gothing motive Which graph(s) show accelerated motion? to go " * slope is changing with the velocity Because acceleration is a change in velocity over a time interval, and velocity is a vector, acceleration is therefore also a vector. ie, when determining acceleration A Vm /s quantitatively, you m/s must include a number, a unit, and a S At S direction. e. g. A race car's acceleration is m/s /s 9.27 m/s2 \\E]. 52 all of these units are the same! m SB1 Motion (second half) Mail bro April 17, 2024 B1.4: Define acceleration, quantitatively, as a change in velocity during a time interval? a = Au Arora : 4-Vi Shop a = VF - V : (section B1.3 of your textbook) What are some examples in your life when you have experienced "acceleration"? plane taking athe speeding up - car starting and slowing down Note: we usually think of acceleration as something speeding up, beviua A but it can also mean that something is slowing down!!!! As long as eved there is a change in velocity (either increasing or decreasing), then there is acceleration happening. 'm accelerating because 'm speeding up I'm accelerating because I'm slowing down. https://youtu.be/qDs7NTx4NRO?list=PLoGgviqq4847W5Jc1K3099YHTGLX- L75m&1=579(stop at 18:30) The four most important facts about acceleration: - an object, taking off Acceleration tells how much an object's speed changes in one second. can describe speed- gravity is fill wanking. When an object speeds up, its acceleration is in the direction of motion no acceleration & motion, When an object slows down, its acceleration is opposite the direction of motion. 9.81 Objects in free fall gain or lose tom's of speed every second. The slope on a velocity-time graph is the acceleration. ( going - 9. 81 mls 2 down )
