Force and motion

The change in velocity as time passes

• Acceleration

• Speed

• Distance

• Displacment

Car moves with take 5 s to cover 100 m then the driver applies break so it take 20 s to stop what is the acceleration

• 1 m/s2

• - 1m/s2

• 2 m/s2

• -2 m/s2

Object move from rest with uniform acceleration 4m/s2 through 6 s find the final velocity

• 20 m/s

• 24 m/s

• 23 m/s

• 10 m/s

Squar with side length 10 m find the distance if you move around it 5 times and return to start point

• 20 m

• 2000 m

• 200 m

• 22 m

Circle with radius 5 m find the displacment if you move half circle

• 25 m

• 15 m

• 10 m

• 5 m

the physical quantity that completely defined by its value only

• scaler

• vector

• displacement

• velocity

find the displacement of an object moves from Cairo to Aswan then to Cairo if the distance between Cairo and Aswan = 900 km

• 1800 km

• 900 km

• 0 km

• none

what is the time needed to reach 5 m/s velocity from rest with acceleration 0.25 m/s2

• 25 s

• 20 s

• 0.5 s

• 1.25 s

deduce the type of velocity from the data:

• uniform velocity

• non uniform velocity

• spontaneous velocity

• average velocity

calculate the velocity from the following graph :

• 5 m /s

• 15 m / s

• 20 m /s

• none
