Which of the following does NOT describe a change in velocity?
A. Your mom drives 60 miled per hour on the freeway.***
B. A kite flies up into the sky, then starts falling down again.
C. Your puppy is running in circles around a large, circular table
D. A boy riding a bicycle hits the brakes snd stops suddenly.
Pls help me I don't know if im right
Your mom drives 60 Miles per hour on the freeway.
To identify which of the given options does NOT describe a change in velocity, we need to understand what velocity is. Velocity is a vector quantity that includes both speed and direction. It indicates the rate at which an object changes its position.
Now, let's examine each option:
A. Your mom drives 60 miles per hour on the freeway.
This option describes a constant velocity, assuming your mom maintains the same speed and direction. Although the speed is mentioned, because the direction and speed remain constant, it does not indicate a change in velocity.
B. A kite flies up into the sky, then starts falling down again.
In this option, the kite changes its direction as it goes upward and then starts moving downward. Since the direction changes, it involves a change in velocity.
C. Your puppy is running in circles around a large, circular table.
Even though the puppy is continuously moving, it is changing direction consistently in a circular path. A change in direction implies a change in velocity.
D. A boy riding a bicycle hits the brakes and stops suddenly.
In this option, the boy is initially moving in a particular direction with specific velocity. However, when he hits the brakes and stops suddenly, he experiences an instantaneous change in velocity since both speed and direction change.
Therefore, the statement that does NOT describe a change in velocity is A. Your mom drives 60 miles per hour on the freeway.
