Can an object have a northward velocity and a southward acceleration? Explain.

Short Answer

Expert verified

Yes, an object moving in a northward direction can have a southward acceleration.

Step by step solution

01

Step 1. Definitions of velocity and acceleration

Velocity is the rate at which an object is displaced from one location to another. Acceleration is the rate at which the object changes its velocity.

02

Step 2. Example for a detailed explanation of the given condition

If the car is moving northward and slowing down, the acceleration is southward (opposite to the direction of motion). When the car slowing down in the northward direction, it is deaccelerating.

03

Step 3. Meaning of deceleration

The velocity of a car moving along the positive y-axis is positive. If the car slows down, the acceleration is negative in the negative y-direction. Deceleration occurs when the magnitude of the velocity decreases and velocity and acceleration point in opposite directions.

Therefore, an object moving in a northward direction can have a southward acceleration.
