Acceleration is the rate of change of velocity with time. Since velocity is a vector, this definition means acceleration is also a vector. When it comes to vectors, direction matters as much as size. In a simple one-dimensional problem like this one, directions are indicated by algebraic sign.

Physical Science: Motion: The Relationships between displacement, time, velocity and acceleration: Displacement, Time and Velocity. PLO C6.
Acceleration Problems. 1. A poorly tuned Geo Metro can accelerate from rest to a speed of 28 m/s in 20 s. a. What is the average acceleration of the car? b. What distance does it travel in this time? 2. At t = 0 a car has a speed of 30 m/s. At t = 6 s its speed is. 14 m/s. What is its average acceleration during this time interval? Time (s) 3.
ACCELERATION PRACTICE PROBLEMS YOU MUST SHOW YOUR WORK. You can use a calculator but you must show all of the steps involved in doing the problem. SHORT ANSWER 1. Does the speedometer of a car read average speed or instantaneous speed? How do you know? 2.
Questions - Acceleration 1. A car accelerates from 20 m/s to 40 m/s in 5 seconds. What is its acceleration? 2. A motorbike speeds up from a standing start (that is, 0 m/s) to 30 m/s in 4 seconds. How fast is its acceleration? 3. When she sees the red traffic light, Marie brakes to a halt from a speed of 70 metres per second in just 2 seconds ...
Acceleration Practice Worksheet. Remember that acceleration is any change in velocity. (Changes in velocity include changes in direction!) How many accelerators are there in a car?
Acceleration is the rate of change of displacement with time. To find acceleration, calculate the slope in each interval. Plot these values as a function of time. Since the acceleration is constant within each interval, the new graph should be made entirely of linked horizontal segments. Displacement is the product of velocity and time.
