graphical representation of moving in straight line

(Distance-time) graph for a regular motion at constant speed is represented by......

• Straight line parallel to time axis

• Straight line parallel to distance axis

• Straight line passing through the origin point

• Straight line cuts the time axis and distance axis

For a car moves at a regular speed, the ratio d/t .......................

• Increases

• Is constant

• Decreases

• Is doubled

The graph ................... representing the object is at rest.

• 
• 
• 
• 

The uniform acceleration means that the object speed ......................... by equal values through equal periods of time

• Increases only

• Decreases only

• Increases or decreases

• Doesn't change

When an object speed is increases, the movement is described as.......................

• Uniform speed

• Decelerating motion

• Zero acceleration

• Accelerating motion

When an object moves with acceleration =zero, this means that the.................

• Object's speed is changed

• Object moves with positive acceleration

• Object moves with deceleration

• Object's speed is constant

Decelerating motion means the.............

• Object speed decreases by time

• Object speed increases by time

• Object speed is constant

• The object is at rest

Acceleration measurement unit is..........

• m/sec

• m.sec

• m/sec ²

• m.sec ²
