PHYSICS URM

URM means:

• Under real motion

• The object doesn´t move

• Uniform rectilinear motion

• Unknown rear motion

In URM speed is constant

• YES

• NO

The unit of speed (velocity) in th SI (International System of UNits) is

• Km/h

• cm/s

• m/s

• km/s

Our blood travels in our body at constant speed of 55 cm/s. Then, its speed is :

• 55 m/s

• 5,5 m/s

• 0.55 m/s

• 0.55 Km/s

A car travels at 20 m/s. How long does it take to travel 1 Km?

• 1 s

• 5 s

• 50 s

• 2000 s

Calculate the distance travel by a car that goes at a speed of 36 Km/h in 15 minutes

• 1800 m

• 3600 m

• 900 m

• 2700 m

URM occurs in straight line:

• NO

• YES

108 km/h is equivalent to:

• 10 m/s

• 30 m/s

• 20 m/s

• 40 m/s

Speed depends on the frame of reference

• No

• Yes

One hour and a half is equivalent to:

• 3600 s

• 1800 s

• 5400 s

• 10500 s
