Which of the following accurately describes an object that is accelerating?
A car slows down to turn a corner.
A bike moving backwards at 3 meters/second.
A ball sitting motionless on the floor.
An airplane moving at 500 km/hr.
see your previous post for the answer to this one.
An object that is accelerating is described as changing its velocity over time. Velocity describes both the speed and direction of an object's motion.
Out of the options given, the only one that accurately describes an object that is accelerating is:
- A car slows down to turn a corner.
When a car slows down to turn a corner, it is changing its velocity. The car's speed decreases, and its direction of motion also changes as it turns. This change in both speed and direction indicates that the car is accelerating.
To identify acceleration, you need to determine if there is a change in velocity. Velocity changes if there is a change in speed, a change in direction, or both. In the case of the car slowing down to turn a corner, both the speed and direction change, making it an example of acceleration.
