Speed, Velocity, and Acceleration Along with displacement, velocity and acceleration round out the holy trinity of kinematics. Speed and Velocity As distance is to displacement, so speed is to velocity: In everyday conversation, we usually say speed when we talk about how fast something is moving.
A common example of speed is the number given by the speedometer in a car. Speed is a measure of the distance an object travels in a given length of time: Velocity is a vector quantity defined as rate of change of the displacement vector over time: Instantaneous Speed and Velocity The two equations given above for speed and velocity discuss only the average speed and average velocity over a given time interval.
Instantaneous velocity is not a tricky concept: Unless a question specifically asks you about the average velocity or speed over a given time interval, you can safely assume that it is asking about the instantaneous velocity at a given moment. Example Which of the follow sentences contains an example of instantaneous velocity?
All three of these requirements are met only in B. A is an example of average velocity, C is an example of instantaneous speed, and both D and E are examples of average speed. Acceleration Speed and velocity only deal with movement at a constant rate. When we speed up, slow down, or change direction, we want to know our acceleration.
Acceleration is a vector quantity that measures the rate of change of the velocity vector with time: Because she is particularly concerned with sleeping as much as possible before the test, she practices the drive the day before so she knows exactly how long it will take and how early she must get up.
Instantaneous Velocity After starting her car, she zeros her odometer so that she can record the exact distance to the test center. Throughout the drive, Andrea is cautious of her speed, which is measured by her speedometer. At first she is careful to drive at exactly 30 miles per hour, as advised by the signs along the road.
Chuckling to herself, she notes that her instantaneous velocity—a vector quantity—is 30 miles per hour due east. Average Acceleration Along the way, Andrea sees a new speed limit sign of 40 miles per hour, so she accelerates. Noting with her trusty wristwatch that it takes her two seconds to change from 30 miles per hour due east to 40 miles per hour due east, Andrea calculates her average acceleration during this time frame: One Way After reaching the tall, black ETS skyscraper, Andrea notes that the test center is exactly 10 miles from her home and that it took her precisely 16 minutes to travel between the two locations.
She does a quick calculation to determine her average velocity during the trip: Average Speed and Velocity: Return Journey Satisfied with her little exercise, Andrea turns the car around to see if she can beat her minute time.
Successful, she arrives home without a speeding ticket in 15 minutes. Andrea calculates her average speed for the entire journey to ETS and back home: Is this the same as her average velocity? Andrea reminds herself that, though her odometer reads 20 miles, her net displacement—and consequently her average velocity over the entire length of the trip—is zero.tranceformingnlp.com Velocity and Speed Compare and Contrast Essay Sample.
