Which of the following is the formula used to solve for the speed of a moving object?

• Speed = distance/time

• Speed = force /time

• Speed = work/ time

• Speed = time/distance

The following are units of measure. Which is used for measuring distance?

• kilogram

• liter

• kilometer

• minute

A car can travel 50 meters in 10 seconds. A fast motorbike can travel 5 meters in a second. A bus can cover 500 meters in 100 seconds. Which vehicle has the highest speed?

• The motorbike has the same speed as the van and the bus.

• The motorbike has the highest speed because it can travel the greatest distance.

• The motorbike has the highest speed because it has the shortest travel time.

• The car has the highest speed because it travels a great distance in a short time.

Suppose the speed of a runner Daniel in the last DCAA Meet was 200 km/hr. Calculate the distance he covered after 2 hours. (Formula: distance = speed X time)

• 300 km

• 400 km

• 500 km

• 600 km

Analyze the situation: A bicycle has an average speed of 2 m/s. This means that ____________.

• it can travel 4 meters in seconds

• it takes 2 seconds to travel 1 meter

• in 1 second, it travels 2 meters

• it can travel 2 kilometers in one hour

Recall why metals are considered good conductors of heat and electricity?

• plants but not metals

• both plants and metals

• metal objects but not through plants

• plants because they keep the amount of heat

Explain why electrical engineers use copper to carry electricity through buildings?
