Question

a car is driving around a curved part of a road as shown below: the dots in the diagram show the location of the car every 1 second as it drives around the curve. they are equal distances apart. consider the car’s motion when it’s at the position shown in the diagram. complete the statement below. • the car dropdown accelerating. this must be true because it is dropdown.

Explanation:

To determine if the car is accelerating, we analyze its motion. Acceleration occurs when there's a change in velocity (speed or direction). The car is moving in a curved path (changing direction) and the dots are equally spaced (constant speed). Since velocity is a vector (includes direction), a change in direction means a change in velocity, hence acceleration. So the car is accelerating because it's changing direction (or moving in a curve).

Answer:

• The car \(\boldsymbol{\text{is}}\) accelerating. This must be true because it is \(\boldsymbol{\text{changing direction (or moving along a curved path)}}\).
