Explain why turning is a form of acceleration?

Acceleration is defined as any change in velocity, which includes both changes in speed and changes in direction. When you turn, you are changing the direction in which you are moving. This change in direction is a change in velocity, and therefore it is a form of acceleration.

To understand why turning is a form of acceleration, let's break it down further. Velocity is a vector quantity, meaning it consists of both magnitude (speed) and direction. When you turn, you are altering the direction component of your velocity vector. Even if your speed remains constant, your velocity is changing, since velocity takes into account both speed and direction.

To experience this acceleration, you can conduct a simple experiment. Take a small object, such as a toy car, and push it forward in a straight line. Note how it moves and the force required to keep it going straight. Then, try making a turn by applying a force towards one side. You will observe that the object resists the change in direction and tends to move in a curved path. This change in direction requires an acceleration, as the object needs to change its velocity vector to follow the curved path.

In summary, turning is a form of acceleration because it involves a change in direction, which alters the velocity vector of an object. Acceleration may not always be related to changes in speed; it can also arise from changes in direction.
