Science 7 Quiz #2 3rd Quarter

What is motion?

• Change in position over time
• Remaining at rest
• Moving in a circular path
• Change in speed only

What is a reference point?

• An object at rest
• The final destination
• The starting point used to measure motion
• A fixed location

How is distance defined?

• Total length of the path traveled
• Shortest path between two points
• Change in position
• Time taken to travel

What is displacement?

• The total path length
• A vector quantity measuring straight-line distance
• The time taken to move
• The speed of the object

How is displacement different from distance?

• Displacement is always positive
• Distance measures straight-line path
• Displacement can be negative
• Distance is a vector quantity

What is the standard unit of distance and displacement?

• Kilometer (km)
• Newton (N)
• Meter (m)
• Second (s)

Can displacement equal distance?

• Yes, only if the path is straight
• No, displacement is always shorter
• No, displacement is always longer
• Yes, if the object returns to the starting point

What happens to displacement if an object returns to its starting point?

• It becomes zero
• It doubles
• It equals the total distance traveled
• It becomes negative

Is displacement a scalar or vector quantity?

• Scalar
• Vector
• Neither
• Both

How is distance calculated for multiple paths?

• Subtracting initial from final position
• Adding all path lengths
• Multiplying the paths
• Dividing total time by distance
