Question

Motion on an incline when you examined an object moving with constant velocity in introductory activity 2.

Option 1: Accelerated motion

Option 2: Decelerated motion

Option 3: Uniformly accelerated motion

Option 4: Uniform motion

Answer 1

On an incline, if an object moves with constant velocity, it is experiencing uniform motion, meaning its velocity remains constant and there is no acceleration along the slope.

Step-by-step explanation:

When analyzing motion on an incline, and noting that the object moves with constant velocity in an introductory activity, we are particularly looking at uniform motion. This term implies that the position of the object is changing at a consistent, unvarying rate. The key characteristic of uniform motion is that its velocity - which includes both speed and direction - does not change over time. This contrasts with accelerated motion, where velocity changes.

In the context of motion on an incline, if the object is indeed moving with a constant velocity, it suggests that the net forces acting on the object are balanced, meaning no net force is causing acceleration or deceleration. This would typically require an external force counteracting gravity, like friction, to keep the velocity constant. When an object is experiencing uniform motion on an incline, its velocity up or down the slope does not change, and there is no acceleration in the direction along the slope.
