What is the force when an objects rolls over a surface?
friction
Rolling friction always reduce the net force acting against an object's motion to zero?
Rolling friction does not reduce the net force acting against an object's motion to zero. Rolling friction is a resistive force that opposes the motion of an object moving along a surface, but it does not completely eliminate the net force. The net force is the vector sum of all forces acting on the object, including rolling friction.
Does rolling friction reduce the net force acting against an object's motion to zero?
maybe
Is it true that rolling friction always reduces the net force acting aginstan objects's motion to zero?
Friction can be reduced, but in most cases there is no practical way to reduce friction to zero.
The force that acts against moving objects is called?
Well, it depends on where and how fast the object is moving. However, forces acting against moving objects would be air resistance (eg. cars or a sky divers), friction (eg. a wheel rolling down a hill), gravity (eg. a ball being thrown into the air)
What is a common unbalanced force acting on objects in motion?
Friction
What force decresses acceleration of two objects moving against each other?
The force that decreases the acceleration of two objects moving against each other is frictional force. Friction acts in the opposite direction to the motion of the objects, creating resistance that impedes their movement. It reduces the net force acting on the objects and consequently decreases their acceleration.
What is friction acting on objects that are not moving?
Friction is holding immobile objects in place.
Is friction acting on a body which is in pure rolling?
yes there is still alittle friction on a ball that is in pure rolling because there is still interaction between the atoms that contact the surface of the ball and the floor
Why does a ball that is rolling come to a stop?
a round object rotates when there is a force acting tangentially.. in this case friction force is acting tangentially... so it should be rolling without stopping.. but it does stop since the weight is not balanced by its normal force(i.e. normal force and weight are not acting on the same point.)
What acts against the direction of th objects motion?
Any force acting in the direction opposite to motion, such as Friction, wind resistance, or swimming up stream
What forces act on a rolling ball?
It acts as a rolling friction or rolling resistance when it starts to roll on a flat surface , it resists the direction of rotation of the object in both clock wise and anti clock wise direction.
