What is a Vector?

Introduction

A vector is a quantity or phenomenon that has two independent properties: magnitude and direction. The term also denotes the mathematical or geometrical representation of such a quantity.

Task

You have to watch video and then answer to the questions on test.

Evaluation

1. What is a scalar?

  •  a quantity that has both magnitude and direction
  • a quantity that only has magnitude and no direction

2. The direction or directions you ran..

  • does have an impact on your displacement
  • doesn't have an impact on your displacement

3. What is a displacement?

  • scalar
  • vector
  • force

4. What is a acceleration?

  • force
  • scalar
  • vector

5. When you push on something, you always push in..

  • particular direction
  • no matter which direction

6. What is an vector?

  • an arrow
  • a quantity that has just direction
  • a quantity that has both magnitude and direction

7. What is the displacement of the cross-country team if they begin at the school, run 10 miles and finish back at the school?

8. What is the distance and the displacement of the race car drivers in the Indy 500?

Conclusion

Answers:

1. a quantity that only has magnitude and no direction

2. does have an impact on your displacement

3. vector

4. vector

5. particular direction

6. a quantity that has both magnitude and direction

7. The displacement of the runners is 0 miles. While they have covered a distance of 10 miles, they are not "out of place" or displaced. They finish where they started. Round-trip motions always have a displacement of 0.

8. The displacement of the cars is somewhere near 0 miles since they virtually finish where they started. Yet the successful cars have covered a distance of 500 miles.
