when ball is kick the force transferred from the foot to the ball and gives the ball a velocity.
Key Terms
- Vectors-a quantity having direction as well as magnatude
- Scalars- having only magnitude,not direction.
- Distance-an amount of space between two things or people.
- Displacement-the moving of something from its place or position.
- Magnitude-the great size or extent of something.
- Resultant-a force, velocity, or other vector quantity that is equivalent to the combined effect of two or more component vectors acting at the same point.
- Vector Addition-the process of finding the geometric sum of a number of vectors by repeated application of the parallelogram law.
Vectors and how they are used
Practice
While looking for your hotel,you drive north 7 miles before turning east and driving for another 5 miles. Find the resultant vector.
Formula you need: a2+b2=c2
substitute: (7^2)+(5^2)=74
Then find the square root of the answer: 8.6 is your final answer!
A vector is a physical quantity that has both direcrion and magnitude.
For example an airplane pilot planning a trip must know how far and which way to fly. Velocity is also a vector quantity. To find the velocity,we must specify both its speed and direction
