Understanding Motion Concepts

What is speed and how is it defined?

• Speed is defined as the force applied to an object.

• Speed is the rate at which an object covers distance, defined as distance divided by time.

• Speed is the total distance traveled regardless of time.

• Speed is a measure of an object's mass.

How do you calculate speed using distance and time?

• speed = time / distance

• speed = distance - time

• speed = distance + time

• speed = distance / time

If a car travels 150 km in 3 hours, what is its speed?

• 30 km/h

• 75 km/h

• 50 km/h

• 100 km/h

What is the formula for calculating distance?

• Distance = Speed - Time

• Distance = Speed + Time

• Distance = Speed × Time

• Distance = Time ÷ Speed

If a runner completes a 400 m lap in 50 seconds, what is their speed?

• 6 m/s

• 10 m/s

• 12 m/s

• 8 m/s

What is the difference between distance and displacement?

• Distance includes direction while displacement does not.

• Distance is the total path length; displacement is the shortest straight-line distance with direction.

• Displacement measures the total distance traveled.

• Distance is always greater than displacement.

If a person walks 3 km east and then 4 km west, what is their displacement?

• 4 km east

• 1 km east

• 1 km west

• 3 km east

How do you calculate time if you know speed and distance?

• time = speed / distance

• time = distance / speed

• time = distance + speed

• time = speed + distance

What is the unit of speed in the metric system?

• feet per second (ft/s)

• meters per second (m/s)

• kilometers per hour (km/h)

• miles per hour (mph)

If a cyclist travels at a speed of 20 km/h for 2 hours, how far do they travel?

• 50 km

• 30 km

• 25 km

• 40 km
