Question

the dot diagram below represents the motion of three objects every time one second has passed. the closer the dot, the slower the motion. the further the dot, the faster the motion. which object is in dynamic equilibrium (moving with constant velocity)? 1 start object 1 object 2 object 3 all of the above none of the above

Explanation:

Step1: Recall constant - velocity property

An object moving with constant velocity has equal displacements in equal time - intervals. In a dot - diagram, this means the dots are evenly spaced.

Step2: Analyze Object 1

The dots of Object 1 are evenly spaced, indicating equal displacements in each 1 - second time - interval.

Step3: Analyze Object 2

The dots of Object 2 are not evenly spaced. The spacing between the dots changes, so it is not moving with a constant velocity.

Step4: Analyze Object 3

The dots of Object 3 are not evenly spaced. The spacing between the dots changes, so it is not moving with a constant velocity.

Answer:

A. OBJECT 1
