Which of the following is not an example of acceleration.
A a person jogging atn3 m/s along a winding path
B a car stopping at a stop sign.
C a cheetah running 27m/s east
D a plane taking off
http://dictionary.reference.com/browse/acceleration
What do you think?
It's essential to remember acceleration as a vector ( having magnitude/size and direction)
So the plane taking off is the easy one to mark off, a cheetah running 27m/s east could be assumed it's speed is constant and not accelerating, a car stopping at a stop sign has a - acceleration( deceleration due to the change in speed over x amount of time) and that leaves a person jogging at 3 m/s along a windy path. Although this speed is constant it's direction is changing, so in physics, technically only A and D are accelerating, however I'm assuming this is not that detailed, so the best guess would be B. Due to "deceleration"
Hope this helps!
To determine which of the following options is not an example of acceleration, we need to understand what acceleration means. Acceleration is the rate at which an object changes its velocity. It can occur when an object speeds up, slows down, or changes direction.
Let's analyze each option to find the one that does not involve acceleration:
A) a person jogging at 3 m/s along a winding path: This involves acceleration because jogging involves changing velocity by increasing speed or changing direction while navigating a winding path.
B) a car stopping at a stop sign: This is an example of negative acceleration, commonly known as deceleration or slowing down. When the car stops, it changes its velocity by reducing its speed, which is a change in acceleration.
C) a cheetah running 27 m/s east: This option involves acceleration because it describes the cheetah running at a constant velocity, but velocity is the result of both speed and direction. As the cheetah changes direction by running east, it is changing its velocity, indicating acceleration.
D) a plane taking off: This option definitely involves acceleration. When a plane takes off, it initially has zero velocity and then increases its speed and gains altitude. This change in velocity indicates acceleration.
After analyzing all the given options, it can be concluded that there is no example that does not involve acceleration. All of the given options describe scenarios where the velocity of the object is changing, which means acceleration is present in each case.
