One more worksheet with questions that I need to have checked!
1.Average speed is the ________ an object travels divided by the ________ it takes. Ans- distance; time
2.The velocity of an object is its ___
in a certain _______. Ans- speed; direction
3.The steepness of the line on a position-time graph measures the object's what? Ans- speed
4.Displacement always includes a _____
and is used in measuring ______. Ans- direction; velocity
Thanks again for the help! -MC
1-3 is correct. Number 4 makes no sense to me.I agree direction, but the second blank makes no sense to me.
Alright, thanks. I'll ask my teacher bout that one

You're welcome! Here's how you can arrive at the answers to each of the questions:
1. To find the average speed, you need to divide the total distance traveled by the total time taken. So, the answer to the first question is: distance; time.
2. Velocity is a vector quantity that includes both speed and direction. So, the answer to the second question is: speed; direction.
3. The steepness of a line on a position-time graph represents the object's speed. You can determine the speed by calculating the slope of the line on the graph. Hence, the answer to the third question is: speed.
4. Displacement is a vector quantity that gives both the magnitude (distance) and direction of an object's change in position. It is used to measure velocity. So, the answer to the fourth question is: direction; velocity.
Remember that it's important to understand the concepts behind these answers rather than just memorizing them.
