Force and Motion EOG Review

How is speed defined in physics?

• The rate at which an object covers distance

• The force exerted by an object

• The path taken by an object

• The potential energy of an object

Solve using the formula speed = distance/time. Distance is 300 km. Time is 5 hours. Speed is ____________

• 60 km/h

• 30 km/h

• 100 km/h

• 75 km/h

Solve using the formula speed = distance/time. Distance is 450 km. Time is 10 hours. Speed is ____________

• 50 km/h

In the DST Triangle, what does 'D' stand for?

• distance

• density

• diameter

• direction

Using the DST Triangle: If you know D (Distance) and T (Time), D is over T so, you will divide. What operation will you use to find the answer?

• Multiply

• Divide

• Add

• Subtract

Using the DST Triangle: A car traveling at a constant speed covers a distance of 750 m in 25 sec. What is the car’s speed? (Give your answer in m/s)

• 30 m/s

• 25 m/s

• 15 m/s

• 20 m/s

A wasp is flying toward you at 8 meters per second (m/s). You are stunned and cannot move. It takes 2 seconds for the wasp to sting you. How far did the wasp travel?

• 16 meters

• 10 meters

• 8 meters

• 4 meters

Using the DST Triangle: In 6 seconds, Jack ran 24 meters. How fast was Jack running?

• 4 meters per second (24 meters ÷ 6 seconds = 4 m/s)

• 6 meters per second

• 3 meters per second

• 2 meters per second

How fast did Jose run 24 meters if it took him 8 seconds?

• 3 m/s

• 2 m/s

• 4 m/s

• 6 m/s

How would you solve for the time it took to travel somewhere if you know the speed?

• time equals distance divided by speed

• time equals speed divided by distance

• time equals speed multiplied by distance

• time equals distance plus speed
