Is Rolling possible on a smooth surface?
Since the values are such that a≠αR, hence rolling motion is not possible on such a surface.
In which situation a body can roll a smooth horizontal surface?
A body can pure roll on a smooth surface only when it is placed on a smooth surface while it was undergoing pure rolling motion or only when conditions of pure rolling are already satisfied.
Can a sphere roll on a smooth inclined surface?
A sphere cannot roll on a smooth inclined surface.
In which situation can a body roll?
Body roll (or lean) happens when you turn into a corner. As your car begins to turn, its weight is thrown to the outside of the corner, causing your car to roll in that direction. Put simply, as you turn left you are thrown to the right and turning right throws you left.
Can an object have an unbalanced force and have a velocity of zero?
Balanced Forces: When forces are in balance, acceleration is zero. Velocity is constant and there is no net or unbalanced force. A plane will fly at constant velocity if the acceleration is zero.
What force must be applied to the block to keep it moving at a constant velocity?
Kinetic friction
Can a moving object have a velocity of zero?
An object in motion continues in motion with the same speed and in the same direction unless acted upon by an unbalanced force.” It is often called the law of inertia. So if You want to move an object with zero velocity, at first moment You have to apply a force slightly bigger than the weight of the box.
Is it possible for an object to have zero velocity yet experience a net force?
An object’s velocity (a vector) does not change if and only if the net force acting on the object is zero. In other words, if there is no net force on an object, its speed and direction of motion do not change (including if it is at rest).
Is it possible for an object to be in motion if no net force is acting on it?
Is it possible for an object to be in motion if no net force is acting on it? yes it is possible because when the net force is zero and acceleration is zero. so if the object has some constant velocity it continues with the same velocity until it has some external acceleration.
What would be the net force on an object if the object’s acceleration is 0?
Acceleration is the change of velocity per unit time, so if there is no force, all we know is that the acceleration is zero. Net force is the vector sum of all forces acting on the object.
