What is velocity? |
Velocity is a vector quantity that signifies the 'magnitude' of the rate of change of position and also the direction of am object's movement. |
|
|
|
What is speed? |

|
|
What is distance? |
Distance is a scalar quantity that refers to "how much ground an object has covered "during its motion |
|
|
|
What is displacement? |

|
What is a resultant vector |
A resultant vector is the vector sum of tow or more vectors. |
|
|
|
Types of vector: Parallel vector |
This is when two vectors are in the same direction and have the same angle but vary in magnitude. |
|
|
|
Types of vector: Anti-Parallel vectors |
Vectors that go in opposite direction. |
|
|
|
Vectors type: Perpendicular vectors |
Two vectors are said to perpendicular if they form a right-angle triangle when they meet. |
|
|
|
How do you find the resultant of a perpendicular vector? |
The Pythagorean theorem : a²+b²=c² |
