Physics Concepts Quiz

What is the main difference between distance and displacement?

• Distance is a vector quantity, while displacement is scalar.

• Distance measures the change in position, while displacement measures the total path length.

• Distance is always positive, while displacement can be negative.

• Distance includes direction, while displacement does not.

How is speed defined in physics?

• Speed is always measured in kilometers per hour.

• Speed is the total distance traveled divided by the total time taken.

• Speed is the rate of change of an object's position.

• Speed is a vector quantity that includes direction.

What is the SI unit for speed?

• Feet per second

• Meters per second

• Miles per hour

• Kilometers per hour

How do you convert speed from kilometers per hour to meters per second?

• Multiply by 3.6

• Divide by 3.6

• Multiply by 1.6

• Divide by 1.6

What distinguishes velocity from speed?

• Velocity is a scalar quantity, while speed is a vector.

• Velocity includes direction, while speed does not.

• Velocity is always greater than speed.

• Velocity is measured in kilometers per hour.

In the case study, what was the average velocity of the object?

• 950 meters per second at a bearing of 210 degrees

• 38 kilometers per hour at a bearing of 210 degrees

• 950 kilometers per hour at a bearing of 210 degrees

• 38 meters per second at a bearing of 210 degrees

What happens to the average velocity if an object returns to its starting position?

• It doubles.

• It remains unchanged.

• It becomes zero.

• It becomes negative.

Which of the following is true about an object's speed?

• It can be negative.

• It is always greater than or equal to zero.

• It includes direction.

• It is always less than velocity.

How is average speed calculated?

• Total displacement divided by total time

• Total distance divided by total time

• Total time divided by total distance

• Total velocity divided by total time

In the sample question, what was Janice's required average speed?

• 0.72 meters per second

• 1.2 kilometers per hour

• 0.10 meters per second

• 0.88 meters per second
