The ball stops after some time due to the force of friction between the ball and the ground. Show Why did the ball rolling on the floor slow down and stop?a ball rolling on the ground slows down and finally stops because of the friction that acts and opposes the motion of the ball . What force cause the ball to stop? friction force What makes the ball stop on rolling after sometime Brainly? Friction makes the ball stop on rolling after sometime When a ball rolls on the ground, for example, friction is created between the ball’s surface and the ground’s surface. This is how friction stops the ball after some time. How friction is a foe?Friction is foe: (i) Friction causes wear and tear in objects. (ii) It causes damage to the parts of machines. (iii) The machines or tools regular maintenance due to which a lot of money is wasted. (iv) It reduces the speed of moving objects, so more force is required. Is both friend and foe?Give examples to show that friction is both a friend and a foe. Answer: Examples to show that friction is a friend and a foe: Friction is friend: (i) Friction allows us to grip and catch different objects. (iii) It helps to minimize the speed or to stop the moving objects. Why does a moving ball come to a stop? Even if the ball is rolling on a perfectly level and frictionless surface it will still come to a stop due to the forces of deformation at the contact patch. The ball deforms as it contacts the surface and the normal force which would be perfectly vertical becomes angled against the direction of motion and brings the ball to a stop. What causes a bouncing ball to stop bouncing? The bouncing ball stops bouncing because of mainly three factors : 1. Friction. 2. Gravity. 3. Decrease in potential energy. When you drop the ball from a certain height, the potential difference is at its extreme point. Why do I keep topping the golf ball?These are the three most common causes of topping the ball, though there are many errors golfers make that create these situations. Most of them are related to your swing mechanics. Now that you understand some of the primary causes related to topping the golf ball, it’s time to address them in a way that helps you improve your golf swing. How much energy does a bouncing ball lose?A bouncing ball is released to freely fall from height h, when it hits the ground it bounces and with every bounce it loses 36% of its energy. In what time will it stop bouncing completely? It it retains 64% of its energy per bounce, it will never run out of energy, no matter how many bounces.

Answer VerifiedHint:Friction is the resistance of one object moving relative to another in response to motion. Like gravity or electromagnetism, it is not a fundamental force. Instead, scientists claim it is the product of the electric attraction between two interacting surfaces between charged particles. Friction is needed in all types of motions. We can walk properly because of friction. Friction is applied on car brakes. Complete answer: Friction is the force that resists the relative motion of rigid objects, layers of air, and components of material sliding against each other. Several forms of friction exist: Dry friction is a force which in contact opposes the relative lateral movement of two solid surfaces. Dry friction between non-moving surfaces and kinetic friction between moving surfaces is subdivided into static friction.The friction between layers of a viscous fluid moving relative to each other is defined by fluid friction. Lubricated friction is an example of fluid friction in which two rigid surfaces are separated by a lubricant fluid. Skin friction is a part of drag, the force that opposes a fluid's motion over a body's surface. Internal friction is the force that resists displacement between the components that make up a rigid object when deformation occurs.When we roll a ball on the ground, the electrons on the surface of the ground in the atoms press against the electrons that hit the ground in the atoms on the surface of our ball. A rolling ball ceases when its motion is resisted by the surface on which it moves. A rolling ball, due to friction, ceases.Hence, option B is correct. Note:The force of friction works between the ball's surface and the surface of the earth as the ball bounces on the ground. The irregularities between the two surfaces are trapped against each other, thereby stopping the ball from travelling forward until an external force pushes it. |
