Acceleration The term acceleration defines the change in velocity that occurs
during a particular period of time. The following formula is used to
calculate acceleration.
Problem: Car Accelerating
Solution: Step 1: In this problem we are given the following: initial velocity = 10 m/s Step 2: Now you have to plug all data into the formula. Note when the problem
has been solved, the units of acceleration are identified as "m/s^{2}
"
Answer: The acceleration of the car is 10
m/s^{2}.
Problem: Airplane starting at rest, then accelerating
Solution: Step 1:
Step 2: Use the formula for acceleration to solve the problem:
30 m/s^{2} x 0.5 seconds = final velocity Answer: The final velocity of the plane is equal to 15 m/s.
