Per 4 Position & Motion Review

Front

What is the definition of motion?

Back

Motion is a change in an object's position over time.

Front

How can you identify a round trip on a position vs. time graph?

Back

A round trip is identified when the graph ends at the X-axis (position = 0).

Front

What three elements are used to describe motion?

Back

Position, direction, and speed.

Front

How do you calculate total distance traveled?

Back

Total distance traveled is determined by adding all the distances of each section together.

Front

What is the formula to find the distance between two points, D and B?

Back

Distance = D's position - B's position.

Front

What is the difference between distance and displacement?

Back

Distance is the total path length traveled, while displacement is the straight-line distance from the starting point to the ending point.

Front

What does a flat line on a position vs. time graph indicate?

Back

A flat line indicates that the object is at rest and not changing its position.

Front

What is speed, and how is it calculated?

Back

Speed is the rate at which an object covers distance, calculated as speed = distance/time.

Front

What is the difference between average speed and instantaneous speed?

Back

Average speed is the total distance divided by total time, while instantaneous speed is the speed of an object at a specific moment.

Front

What does a negative slope on a position vs. time graph represent?

Back

A negative slope indicates that the object is moving in the opposite direction.
