Question

Give an example for : speed changes with direction remaining constant

Answer 1

if a car turns a corner at constant speed it is accelerating because its direction is changing

Answer 2

The motion of a cyclist on a circular track is an example that shows that when the speed changes direction remains constant.

Explanation:

• Speed increases when an object is moving on a straight road.
• In an instant if the speed increases and direction remains the same then one can tell the object is moving on a straight road.
• In Uniform circular motion the direction changes at every point.
• Body will be in constant motion and constant velocity.
• But in a uniform circular motion, the speed remains constant but the velocity keeps changing.

• The motion of a cyclist on a circular track is an example that shows that when the speed changes direction remains constant.
• We can change direction at a constant speed and thus, any change in velocity will mean an acceleration takes place.
