motion in one direction part 3

The concept of body movements means......

• Constancy of its position with the change in time

• The change in its position with the time

• Its speed

• Its acceleration

The distance covered by a moving body through a unit time is called the .................of the body

• Density

• Speed

• Motion

Speed measuring unit is............

• Meter.second

• Meter/second

• Meter/second²

• Kg

A train moves at a speed 100 km/h, this means that it covers a distance of 50 km within time ............... hours

• 0.3

• 0.4

• 0.5

• 0.6

When moving object covers equal distance in equal periods of time, this means that the object moves at .................

• Uniform speed

• Uniform acceleration

• Average speed

• Relative speed

A car covers a 180 meters in 2 seconds, so its speed equals.................

• 90 meter/sec.

• 180 km/h

• 20 m/sec

• 25 m /sec

• 18 m/sec

• 40 m/sec

When the body covers equal distance at unequal intervals of time, this means that the body moves in......................

• Non uniform speed
