Speed, Distance & Displacement

What two measurements are necessary for calculating speed?

• Mass and time
• Temperature and mass
• Mass and distance
• Distance and time

What is the speed of an object that travels 60 meters in 4 seconds?

• 240 m/s
• 15 m/s
• 0.067 m/s
• 15 mph

A measurement of how fast an object is moving

• Velocity
• Speed
• Vector
• Acceleration

Total distance divided by total time, for an object shows:

• acceleration

• the size of one's toupee

• absolute speed

• average speed

• 10 m/s
• 1000 m/s
• 100 seconds
• 10 seconds

What is the equation to calculate speed?

• speed = distance/time
• speed = time/distance
• speed = time x distance 
• speed = speed/time
