Motion Quiz 1

displacement

• the change in position of an object

• the amount of space between one point and another

• the speed and direction of moving objects

• the point or place where something begins

What is velocity?

• The distance an object travels per unit of time.

• The change in position of an object.

• Speed in a given direction.

• The state in which one objects distance from another is changing.

Motion

• The starting point you use to describe the motion or position of an object.

• The object's distance and direction from a reference point.

• The process of changing position.

• The difference between the initial, or starting, position and the final position of an object that has moved.

What is the equation to calculate speed?

• speed = time ÷ distance

• speed = distance ÷ time

• speed = distance × time

• speed = distance × velocity

How far will a person go if they jog for 2 hours at a speed of 12 km/hr?

• 6 km
• 0.5 km
• 10 km
• 24 km

Which of the following is a unit of speed ?

• sec
• mi
• m/s
• min

Which of the following is a unit of time?

• sec
• mi
• m/s
• km

What is the difference between instantaneous speed and average speed?

• Average speed happens in a particular instant, Instantaneous speed is the speed of an object over a longer period of time.
• Instantaneous speed is never right, average speed is always right
• Instantaneous speed happens in a particular instant, Average speed is the speed of an object over a longer period of time.
• Do not pick this answer

Which is true?

• Speed is measured in m/s but velocity is measured in s/m

• Speed is a vector and velocity is a scalar

• Speed and velocity are the same exact thing

• Speed is like velocity but without a direction

What is a difference between distance and displacement

• Distance is measured in seconds and displacement is measured in meters

• Distance is always shorter than displacement

• Displacement can be equal to zero if the object ends in the place it began in

• Distance can be equal to infinite when only a small distance has been travelled
