A straight line with a positive slope on a velocity-time graph indicates which of the following?
no movement
constant acceleration toward the reference
constant velocity away from the reference
constant acceleration away from the reference
Well, straight lines can be pretty boring, right? But don't worry, I won't clown around with this one!
A straight line with a positive slope on a velocity-time graph indicates constant acceleration toward the reference. It means that the object is speeding up in the positive direction over time. So, no clowning around here! It's all about that acceleration!
A straight line with a positive slope on a velocity-time graph indicates constant acceleration away from the reference.
To determine the correct answer, we need to understand how a velocity-time graph represents the motion of an object. The slope of the line on the graph represents the object's acceleration.
Considering the given options:
- "No movement" would be represented by a horizontal line with zero slope on the velocity-time graph.
- "Constant velocity away from the reference" would be represented by a straight line with zero slope on the velocity-time graph.
- "Constant acceleration away from the reference" would be represented by a straight line with a positive slope on the velocity-time graph.
Hence, the correct answer is "constant acceleration away from the reference." This means that the object is moving away from the reference point with a consistent increase in speed over time.
constant slope means constant speed.
positive speed means increasing distance.
So, which direction has the distance always increasing?
