• Displacement

• Distance

• Motion

• Time

Which refers to the shortest distance between to object’s two positions?

• Displacement

• Distance

• Motion

• Time

The change in position over an interval of time is called ________.

• Displacement

• Distance

• Motion

• Time

The distance travelled by an object, how fast the object is travelling, and the direction in which the object travels, are measured concerning _________.

• Displacement

• Distance

• Motion

• Reference Point

Which of the following is defined as the displacement covered per unit of time?

• Acceleration

• Displacement

• Speed

• Velocity

Which of the following is a unit of speed?

• Meter

• Second

• Meter/Second

• Meter/Second/Second

What is shown when you look at the speedometer in a moving car?

• Average speed

• Average acceleration

• Instantaneous speed

• Instantaneous acceleration

Which of the following statements refers to velocity?

I. Boy walks 30m east        III. The ball rolls 10 m/s north

II. Car runs 40 m/s west    IV. Air moves 100 km/hr

• I only

• II only 

• II and III only

• II, III and IV only

Which of the following statements is NOT true about the object moving with constant speed?  

• The object is not accelerating

• The speed of the object is equal to zero.

• The distance traveled by the object increases uniformly.

• The speed of the object remains the same throughout the travel.

Lexi was asked by her teacher how to solve the speed of an object. She said that to solve for the speed of an object, one must multiply the distance travelled by the recorded time of travel. Do you think her process is correct?

• Yes, because multiplication is the way to solve for speed.

• Yes, because she had all the needed data like distance and time.

• No, because in solving for speed one must divide the distance travelled by the recorded time of travel.

• No, because in solving for speed one must add the recorded time and the distance traveled.
