5 Questions
Which of the following statements about velocity in circular motion is true?
Velocity is always changing in circular motion.
What is true about the speed of an object moving in a circle?
The speed is always constant in circular motion.
What happens to the direction of travel in circular motion?
The direction of travel is always changing in circular motion.
What causes an object to change direction in circular motion?
Force acting at 90 degrees to the object's direction of travel
What happens to the speed in circular motion when the direction of travel changes?
The speed remains constant
Study Notes
Circular Motion
- Velocity is constantly changing in circular motion due to the change in direction.
- The speed of an object moving in a circle remains constant, but the direction of motion changes continuously.
- The direction of travel in circular motion is constantly changing, which means the object is accelerating.
- An object changes direction in circular motion due to a force acting perpendicular to the direction of motion, causing the object to turn.
- The speed of an object in circular motion remains constant, but the direction of motion changes, resulting in a continuous change in velocity.
