Generally, only two forces act on a rolling ball. Gravity and friction (there has to be friction because without it, the ball would just slide). These are pointed directly in the x and y directions. If the ball is rolling down a slope, you can use trigonometry to find the force components.

Are gears an example of rolling friction?
Gears are not perfect example for rolling friction. Most energy lost in gear operation is due to the surface shear stress, which is more like sliding friction. Rolling friction is due to the pressure induced torque applied on the roll axis. Under this circumstance, the equivalent pressure force doesn't point to the roll axis, which creates a torque to resist the rolling motion. A good example for rolling friction can be a running wheel of the car.
Is a ball rolling in a straight line at a constant speed in equilibrium?
Yes. Because it is moving at a constant speed, we know that it is not accelerating (changing its speed). This means that all forces acting on it are balancing each other, so the net force is 0.
What is the unbalanced force of kicking a ball back and forth to each other?
1) While the ball is kicked, the main force is the force of the foot against the ball.2) While the ball is in the air, the main force acting on the ball - again, an unbalanced force - is gravity.
What would happen if there were no friction between a rolling ball and the ground?
A tire has grip on it and so does a road so they can grip onto each other and the car can move. If there was no friction, then the cars wheels would spin, but the car woud not move as there is nothing for it to hold onto
If a golf ball and a bowling ball are rolled toward each other when they collide and the bowling ball stops how does the golf balls speed compare with the bowling balls speed?
the golf ball stopped but the bowling ball keep rolling due to their different size and weight.as we know bowling ball is bigger in size as well as weight so it will face more fictin force and stops early as compare to golf ball when they collide and at the same time bowling ball poshes the golf ball back.so the golf ball stops and the golf ball keeps rolling.
Why don't a basketball player and ball pull towards each other?
A basketball player and the ball do not pull towards each other because the force of gravity between them is very small compared to the force of the player's hand holding the ball. The player's hand exerts a much stronger force on the ball, preventing them from pulling towards each other.
What force causes the ball to fall to the ground?
The force that causes the ball to fall to the ground is gravity. Gravity is a natural force that attracts objects towards each other, and in the case of the ball falling, it is being pulled towards the Earth's center by the force of gravity.
Identify the action reaction force pair involved when you catch a ball?
When you catch a ball, the action force is the force applied by your hand on the ball to stop its motion. The reaction force is the force applied by the ball on your hand in the opposite direction, creating an equilibrium that allows you to catch the ball securely.
Why do equal but opposite forces not cancel each other out when you hit a ball?
When i hit a ball i.e. we give a force in the ball,the ball give an equal & opposite force in our hand..as the two forces acting in the two different bodies so the equal and opposite forces cannot balance with each other..
What do the equal action and reaction forces do not cancel each other when one person hits a ball?
The equal action and reaction forces do not cancel each other out when one person hits a ball because they act on different objects. The force exerted by the person hitting the ball causes the ball to accelerate in the direction of the force, while the reaction force from the ball pushes back on the person, causing them to feel the impact of hitting the ball.
Which is easier to stop sliding or rolling friction?
== == AnswersIt is easier to stop sliding friction than rolling friction. The force due to sliding friction will always be greater than the force due to rolling friction. And since friction force will be in the opposite direction of motion it will be easier to stop an object in motion that is sliding than one that is rolling.
Explain why the equal action and reaction forces do not cancel each other when one person hits the ball?
It does work. The force of a person hitting a ball "cancels" out the force of the ball moving and brings it to a stop (to zero). Only then does the ball move in the direction it is hit, due to the overwhelming force applied by the person.
