There are two types of drag experienced by a sphere. The first is the obvious drag due to friction. This only accounts for a small part of the drag experienced by a ball. The majority of the drag comes from the separation of the flow behind the ball and is known as pressure drag due to separation. For laminar flow past a sphere, the flow separates very early. The surface roughness caused the flow to transition from laminar to turbulent. The turbulent flow has more energy than the laminar flow and thus, the flow stays attached longer.
Yes Friction between the wheels and the ramp and also friction between the body of the car and the air (unless the car and ramp are in a perfect vacuum) There will be additional friction in the bearings or ball race of the wheel / axle too
The two main reasons are (1) the collision is inelastic and (2) friction. Both these factors reduce the ball's energy.
It will not, unless it is acted upon another force. If it's rolling on something, then friction will stop it (the ball rubbing on the table slows it down).
Because the rough road has more friction, thus expending the balls energy quicker than smooth road with less friction.
It's speed will reduce to to friction by gravity.
If friction did not exist, the ball would continue rolling indefinitely without slowing down or stopping. Friction is the force that opposes motion on surfaces, so without it, the ball would not experience any resistance to slow it down.
actually volleyball has alot to do with friction. when you are getting ready to hit the ball there is friction between the floor and your feet. then, when you hit the ball there is friction between your feet and the floor but also between your hands and the ball. now is the ball goes low and you hit it you would be using alot of friction because there would be friction between your body and the floor, the volley ball and your hands and maybe the ball and the floor. hope this answers your question!
When you throw a ball, a force called the applied force is exerted on the ball by your hand. This force propels the ball forward and gives it the initial velocity. Additionally, air resistance and gravity act on the ball as it moves through the air.
The two types of friction that occur when rolling a ball from the top of a hill to the bottom are kinetic friction between the ball and the surface it rolls on and air resistance as the ball moves through the air.
The metal ball would travel faster through water at 15 degrees Celsius, as colder water has lower friction compared to warmer water. This results in less resistance for the ball, allowing it to move more easily through the water at a higher speed.
If there were no friction or obstacles, the ball would roll in a straight line indefinitely due to inertia. Without any forces acting upon it, the ball would maintain its velocity and direction.
Friction between the cotton ball and the walls of the tube can influence the speed at which the cotton ball falls. More friction means more resistance, which can slow down the cotton ball's descent. If there's less friction, the cotton ball can fall more freely and quickly through the tube.
Friction between the ball and the surface it is rolling on will slow down the ball's motion by converting some of its kinetic energy into heat. As a result, the ball will roll for a shorter distance and with a lower speed compared to a scenario with minimal friction.
When a ball is kicked, it undergoes both static friction as it grips the ground before being kicked, and kinetic friction as it moves through the air and comes into contact with the surrounding air particles.
Friction keeps you from flying off the court.
no
Yes it would. Speed will depend on Weight of the ball, Incline angle, Friction, and air pressure.
