- nuke it a few times.

- make your fruends hold it.
How do you stop a rolling ball?
When you roll a ball on the ground, the electrons in the atoms on the surface of the ground push against the electrons in the atoms on the surface of your ball that is touching the ground. A rolling ball stops because the surface on which it rolls resists its motion. A rolling ball stops
because of friction
.
When a ball is rolling down a hill?
As the ball rolls up the hill
its velocity is negative
(because of how the x axis is defined) and decreasing in magnitude (a smaller negative number). At the top of the hill, its velocity is zero, and as it travels down the hill, the ball is speeding up. Therefore, its speed decreases, reaches zero, and then increases.
What force slows the golf ball as it rolled down the hill?
The ball will slow down due to
friction
while moving across the level surface and it will speed up due to the parallel component of the weight vector while moving down the incline.
Why do balls stop rolling?
Friction
– as the ball rolls, the ball loses its energy to heat and sound. As the energy is lost, the ball slows down and eventually stops. … A rolling ball stops because of friction.” ScienceLine.
What makes the ball keeps on rolling?
When a rigid ball rolls on a plane with no other forces, it is known that
no friction applies
and the ball keeps rolling.
Why do things roll down a hill?
A:
Gravity
tries to pull things to the center of the earth. … If the ground is sloped, like on the sides of a hill, the object being pulled at by gravity (a ball for example) can get closer to the center of the earth by rolling to the bottom of the hill.
Why doesnt the ball roll up the hill?
If you place a ball on the top of the left hill, it is high up, so it has potential energy. … So a
ball must have kinetic energy
to roll uphill. A ball that’s not moving won’t just start rolling uphill on its own. It doesn’t have the energy.
Why is a ball rolling down a hill considered unbalanced?
-An object at rest will remain at rest and an object in motion will remain in motion until an unbalanced force acts upon them. (Ex~A ball will roll down a hill, but will eventually stop
because of friction
.) … -Force depends on mass and acceleration.
How does friction affect a ball rolling down a ramp?
With friction, there is
both translational and rotational kinetic energy
as the ball rolls down the ramp. When there is no slippage, the ball slides down the ramp with no rotation.
Is a ball rolling down a hill An example of kinetic energy?
A ball rolling down a hill is converting potential energy (height above a point in a gravity field) into
kinetic
energy (energy of a moving mass.) The kinetic energy is made up of rotational (spinning) and translational (moving relative to the ground.)
Why does a ball rolling along the ground stop after some time?
The ball stops after some time
due to the force of friction between the ball and the ground
.
Why does a ball roll faster down a steep slope?
This is because moving up or down a hill changes one kind of energy into another.
Objects at the bottom of the hill have more kinetic energy
, which means they are moving faster.
What force causes the ball to roll down the ramp?
The
force of gravity
points straight down, but a ball rolling down a ramp doesn’t go straight down, it follows the ramp. Therefore, only the component of the gravitational force which points along the direction of the ball’s motion can accelerate the ball.
What force stops motion?
Friction
is a force that slows or stops motion. Friction is the resistance to motion created by two objects rubbing against each other (the sled and the snow, for instance).
What will cause the ball’s motion to start what will cause the ball’s motion to stop?
What forces caused the ball’s motion? …
The force of the hill
caused the ball to roll down it but gravity caused the ball to slow down and stop. Gravity caused the ball to roll down the hill but friction caused the ball to slow down and stop.
How do balanced and unbalanced forces affect the motion of an object?
Balanced forces do not result in any change in motion
. forces: forces applied to an object in opposite directions that are not equal in size. Unbalanced forces result in a change in motion.
How does friction affect rolling?
A wheel or ball on a surface is held there by static sliding friction. … The force of the static sliding friction
prevents the wheel from sliding and thus initiates
the rolling motion. The rolling motion is actually a form tilting about the point in contact.
How can balanced forces cause rotation?
Assuming the connection between the stick and the fulcrum stays firm, this force has no effect. (It is balanced by a sideways force between the fulcrum and the stick.)
The component of the string tension force perpendicular to the meter stick
acts to cause rotation in the usual way.
Does ball rolling down hill have friction?
Friction, in a general sense, is a force that opposes motion. A force is a push or pull. So, if the ball is rolling down the
hill then friction is opposing the ball’s motion down the hill
. So you can think of friction as a force in the opposite direction of the ball’s motion.
Can a ball roll without friction?
So static friction is infact necessary for a ball to begin rolling. from this the top of the ball will move at speed 2v the centre of mass of the ball will move at v and the bottom edge of the ball will instantaneously be at rest. So as
the edge touching the ground is stationary it experiences no friction
.
Which ball moves faster Why?
If two objects have the same mass and a greater force is applied to one of the objects,
the object which receives the greater force will change
speeds more quickly. For example if a ball is hit harder, it will speed up faster.
Where does a ball rolling down a hill have the most kinetic energy?
Kinetic energy is greatest
immediately after you stop doing
work to get the ball rolling. Maximum gravitational potential energy could occur at either the top of the first hill, or at the ball’s highest point on the second hill, depending on circumstances.
When a ball rolls down hill its potential energy and its kinetic energy?
If you place a ball on the top of the left hill, it is high up, so it has potential energy. Now, if you allow it to roll down the hill, it changes that
potential energy into kinetic energy
(it gets less high and starts to roll faster). …
What kind of kinetic energy is a rolling ball?
For example, a ball that is dropped only has translational kinetic energy. However, a ball that rolls down a ramp rotates as it travels downward. The ball has
rotational kinetic energy
from the rotation about its axis and translational kinetic energy from its translational motion.
