C10IGP- Motion Weekly-1

Which of the following is a vector quantity?

• Work

• Speed

• Velocity

• Force

• Accelaration

Speed =

• distance / time
• time / distance
• distance * time

Acceleration is

• increasing speed
• decreasing speed
• changing direction
• all of the above

A car starts from rest at a stop light and reaches 20 m/s in 3.5 s. Determine the acceleration of the car.

• 2.2m/s²
• 7.0m/s²
• 5.7m/s²
• 70m/s²

What is velocity?

• the quickness of an object
• the location of an object
• acceleration
• speed in a specific direction

How can you find the distance around a circle?

• 2πr

• d/t

• v²

• T

Negative displacement means:

• Retardation

• object is moving forward

• object is moving in opposite direction

• object is coming to rest

• Deacceleration

choose the correct formulas:

(related to speed)

• speed = distance/time

• distance = speed*time

• time = distance/speed

• average speed = total distance/total time

• speed = displacement/time

Choose the correct formulas:

(related to velocity)

• velocity = displacement/time

• velocity= diplacement/time

• acceleration = change of velocity/time

• uniform velocity = final velocity+initial velocity/2

• non-uniform velocity = total displacement/ total time

negative acceleration is:

• Retardation

• object is moving forward

• object is moving in opposite direction

• object is coming to rest

• Deacceleration
