Kinematics 1

Scalar quantities have only ​ (a)  

• magnitude
• direction

Examples of scalar quantities include ​ (a)   , ​ (b)   , mass, energy and time

• distance
• displacement
• speed
• velocity

Vector quantities Have both magnitude and ....

Total length covered by moving object, along the path taken is called by ....

Straight-line distance covered by moving object, regardless of path taken is called by ....

Look at the picture!

What is the distance travelled from A to F? .... m

Look at the picture!

What is the displacement from A to F? .... m

Displacement is a vector quantity. For an object moving in a straight line, assign one direction from the reference point as ​ (a)  

• positive
• negative
• neutral

Dispacement is a vector quantity. For an object moving in a straight line, assign opposite from the reference point as​ (a)  

• negative
• positive
• neutral

Speed is the (a)   moved per unit (b)  

• distance
• time
• displacement
• second
• hour
• meter
• km
