Define uniform circular motion.
Show hintHide hint
Think of movements like a car on a racetrack.
Question 2.
What does centripetal acceleration depend on?
Show hintHide hint
Look at the formula for acceleration.
3Question 3.
What indicates that an object is in uniform circular motion?
- Constant speed in a straight line
- Constant speed in a circular path
- Varying speed
Show hintHide hint
Focus on both speed and type of path.
4Question 4.
True or False: Centripetal acceleration always points away from the center of the circle.
- True
- False
Show hintHide hint
Think about the direction of the forces involved.
Question 5.
A ball is swung in a circle with a radius of 2 m at a speed of 4 m/s. Calculate the centripetal acceleration and angular speed.
Show hintHide hint
Use the formulas for centripetal acceleration and angular speed.
Question 6.
An object moves in a circle of radius 10 m. If it completes one revolution every 5 seconds, calculate its linear speed and centripetal acceleration.
Show hintHide hint
Remember to calculate the circumference and use it for speed.
