What forces act on a tetherball?
There are two forces acting on a tether ball as it rotates in uniform circular motion. 2. The force of tension acts along the rope while the weight acts straight down. The force of tension provides the center seeking force and is the horizontal component of the Ft.
How does tether ball work?
Tetherball is a game where two players use their hands to strike a volleyball which is suspended from stationary metal pole by a rope or tether. The game ends when one player manages to wind the ball all the way around the pole so that it is stopped by the rope. It must not bounce.
What is the centripetal force in tetherball?
The motion of a tetherball is governed by two forces. These two forces combine to generate a net force, i.e. centripetal force. Since the ball’s weight hasn’t changed, the angle of the tension force changes until the ball is in vertical equilibrium.
What is a tether in tetherball?
The ball that is hung by a nylon rope, or tether, from the top of the pole is similar to a volleyball. The length of the rope is long enough to allow the ball to hang two feet from the ground when not wrapped around the pole.
How do you find the tension in a vertical circle?
Motion in a Vertical Circle
- For a mass moving in a vertical circle of radius r = m,
- For a velocity at the top vtop = m/s.
- the velocity at the bottom is vbottom = m/s.
- For a mass m = kg,
- the tension at the top of the circle is Ttop = Newtons.
- The corresponding tension at the bottom of the circle is Tbottom = Newtons.
Are you allowed to grab the ball in tetherball?
5. Only players outside the circle may throw & catch the ball. Inside players may not catch the ball.
Can you kick a tetherball?
You can hit it directly off your hand, or toss the ball and hit it. Important: The server can’t hit the ball again until the opposing player hits it back in the other direction or the ball wraps around the pole 4 times.
What is the tension at least position when performing vertical circular motion?
tension acts radially inward while weight radially outward. here, v = √(5gh), it is velocity at Lowest position in case of string. now, difference in tension at lowest and uttermost point for a particle performing vertical circular motion = T’ – T = 6mg.
What are the rules of the tetherball game?
Although the rules of the game may vary, the object of the game is to hit the tetherball in one direction and wrap the rope completely around the pole so that the ball stops. The two players decide who will serve the ball first.
What kind of equipment is used for tetherball?
While not officially recognized as a sport, it is typically an outdoor activity. The equipment consists of a stationary metal pole, from which is hung a volleyball from a rope or tether. The two players stand on opposite sides of the pole.
How is a tether ball secured to the ground?
Tetherball. The pole is secured firmly into the ground usually with cement, although there are portable versions that are deemed a safety hazard by some because they are less sturdy for play. The ball that is hung by a nylon rope, or tether, from the top of the pole is similar to a volleyball.
What’s the difference between tether ball and soccer?
Tetherball is not soccer, so kicking the ball is prohibited. Do not hit the ball with your elbows, knees, head, or any part other than your hands. Also, do not use foreign objects to hit the ball. In tetherball, “juggling” is keeping the ball in your position by holding it or administering multiple hits.
