Use distance to describe the total path between starting and ending points, and use displacement to describe the shortest path between starting and ending points. Measurement from your initial position to your final position is distance traveled, and the measurement of the total length of your path from the starting position to the final ...

The variables include acceleration (a), time (t), displacement (d), final velocity (vf), and initial velocity (vi). If values of three variables are known, then the others can be calculated using the equations. This page demonstrates the process with 20 sample problems and accompanying solutions.
16. A body travelling along a straight line traversed one-half of the total distance with velocity v 0. The remaining part of the distance was covered with a velocity v 1, for half the time and with velocity v 2 for the other half of time. Find the mean velocity averaged over the whole time of motion. Sol. Let total distance = x
2. A physics book is moved once around the perimeter of a table of dimensions 1.0m by 2.0 m. a. If the book ends up in its initial position, what is its displacement? b. What is the distance traveled? 3. Light from the sun reaches the Earth in 8.3 minutes. The velocity of light is 3.00 x 10 8 m/s. How far from Earth is the sun? 4.
One simple way to calculate the distance covered is to use the formula for average velocity: vavg = distance or vavg = ∆x time t Find the distance covered by a car moving at an average velocity of 12 m/s for 4.0 seconds. 12 = ∆x. 4.0. ∆x = 12 (4.0) = 48 m. Over an 8.0 second period, its velocity changes from 15 m/s.
A tennis ball thrown at a velocity of 25.0 m/s at 53.1° lands exactly 3.00s later on the top of a building. Calculate the horizontal distance it traveled and the height of the building. 9. **A golfer can drive a ball with an initial speed of 30.0 m/s.
Worksheet 1a – Distance and displacement 1. Frank is driving along a straight highway when he notices a marker that says “260km”. He continues to the 150-km marker and then turns around and goes back to the 175-km marker. a) What is the total distance travelled? b) What is the total displacement for the whole trip? 2.
