Swinging a ball on a string around your head demonstrates the concept of centripetal force, where the force is directed towards the center of the circular motion to keep the ball moving in a curved path. This creates tension in the string to prevent the ball from flying off. The speed and distance of the ball depend on the force applied and the length of the string.

Swinging a ball on a string around your head is what law?
Swinging a ball on a string around your head demonstrates Newton's first law of motion, also known as the law of inertia. The ball's natural tendency is to stay at rest or continue moving at a constant speed in a straight line unless acted upon by an external force (in this case, the tension in the string).
A billiard ball will stop short when it collides head-on with a ball at rest the ball cannot stop short however if the collision is not exactly head on why?
The momemtum trasnsferred is only partial, mvcos(angle). If angle is not zero, there is momentum not transfered and thus left to move the incident ball.
What is lighter than a golf ball?
A pingpong ball. There much lighter like if i throw them at my head with my shotgun it will not hurt much.
A 30 g ball is fired horizontally with initial speed v0 toward a 85 g ball that is hanging motionless from a 1.2 m long string. The balls undergo a head-on perfectly elastic collision after which the?
After the collision, the 30 g ball will come to a stop as it transfers its entire momentum to the 85 g ball, causing it to swing upwards. The final velocity of the 85 g ball can be calculated using conservation of momentum and conservation of energy principles. The maximum height the 85 g ball will reach can also be determined by equating the initial kinetic energy of the system to the potential energy at the maximum height reached.
When a footballer heads a ball his head puts a force on it This force affects the ball in 3 ways What are they?
1) speed 2) direction 3) shape

Do you lose if you scratch in pool table on your brake?
No, you do not lose. When you scratch on the break, your opponent has ball in hand behind the head string. == If a player scratches on a legal break shot, (1) all balls pocketed remain pocketed (exception, the 8-ball: see rule 4.8), (2) it is a foul, (3) the table is open. Please Note: The incoming player has cue ball in hand behind the head string and may not shoot an object ball that is behind the head string, unless he first shoots the cue ball past the head string and causes the cue ball to come back behind the head string and hit the object ball."
Where is the head string located in a pool?
The head string in a pool is located at the opposite end of the rack from where the cue ball is placed for the break shot.
What is the difference between a curved 3rd shoting string and a regular one in lacrosse?
A curved third shooting string guidesthe ball out up the center of the of the head, whereas the straight third string the ball could fly out anywhere.
Is a ball twirling around someone's head rotating or orbiting?
ball spinning on its axis- rotation ball spinning around the head- revolution/ orbiting
What is woven in the head of the racquet and used to hit the ball?
The string is woven into the godhead of a racquet and used to hit the ball.
What would happen to an object if the centripetal force acting on it stops?
Picture a ball on a string being whirled about the head of an experimenter. If the string breaks, the centripetal force disappears. The ball leaves on a tangent path form its (previous) circular path. Yes, it's that simple. The string provided centripetal force, by virtue of its tensile strength, to the ball to keep that ball moving in a circle. When the string broke, there was no force left to accelerate the ball "in" and keep it moving in an arc.
What is the purpose of the head string in pool?
The purpose of the head string in pool is to establish the starting point for the cue ball to be placed before a player's turn. It helps ensure a consistent and fair starting position for each player during the game.
Do you have to move the cue ball after scratching in a game of pool"?
Yes, in a game of pool, if you scratch (pocket the cue ball) you must move the cue ball to the "kitchen" (behind the head string) for the next player's turn.
What equations describe centripetal acceleration centripetal force and gravitational force?
Centripical acceleration is the acceleration toward the centre that holds a satellite in elliptical orbit. All three are basically the same, all are attractied to a common center. They can be demonstrated by swinging an object around your head held by a length of string.
Where to place cue ball on break?
The cue ball must be placed prior to the head string. The head string is the imaginary line connecting the second diamonds on the rails at the end the break is made from. The area between the head string and the rail closest to the breaking player is called the "kitchen". The balls are racked at the center of the foot string, at the other end. Where to place the cue ball wthin the kitchen depends on the game, how well the player is skilled at doing a break shot, and personal preference (usually, where the best chance is to win on the break). For newer players, the cue ball is best placed close to the rail so that a rail bridge can be used. This can be the fastest and most accurate for newer players. For players looking for a fast and powerful break without specifically trying to pocket the 8 or 9 ball on the break, the cue ball is placed relatively near the center and close to the head string, as they will strike only the first ball. For player wanting the best chance of sinking the 8 or 9 on the break, the cue ball will be placed next to, or within a few inches of, the side rail and near the head string. The player will striking both the first and second balls in the rack, proven to have a very high chance of producing a win on the break. Exactly wear to hit, the hit and stroke on the cue ball, and cue ball placement should be studied by watching successful professionals.
How do you throw a dodgeball?
Hold the ball in your hand then make an upward motion above your head and release when your hand is just above your eyes and follow through by swinging your arm back down.
