Question

Magnitude of the instantaneous acceleration decreasing suggests that the object is:

A. Speeding up
B. Slowing down
C. Moving at a constant speed
D. Not in motion

Answer 1

Magnitude of the instantaneous acceleration decreasing suggests that the object is slowing down.

Step-by-step explanation:

Acceleration is a vector quantity that describes the rate of change of velocity of an object per unit of time. It involves both a change in the object's speed (magnitude of velocity) and a change in its direction. Acceleration is denoted by the symbol a and is measured in units such as meters per second squared (m/s²) in the International System of Units (SI).

The decreasing magnitude of the instantaneous acceleration suggests that the object is slowing down. When an object's acceleration is in the opposite direction of its motion, it slows down or decelerates. This can be seen in situations where the acceleration vs. time graph is a horizontal line at some negative value.
