How will the velocity of the book change as it moves across a surface with no friction?
The velocity of the book will remain constant as it moves across a surface with no friction.
When an object is pulled across a level surface at a constant velocity what force is the pulling force equal too?
The pulling force is equal to the force of friction acting in the opposite direction. At constant velocity, the force of friction is equal in magnitude but opposite in direction to the pulling force, resulting in a net force of zero and thus no acceleration.
How will the velocity of the book change as it moves across the surface with friction?
The velocity of the book will decrease as it moves across the surface with friction. Friction acts in the opposite direction of motion, slowing down the book.
Boy is pushing a 30 kg box across the floor at a constant velocity of 0.5 ms. How much work in Joules is done by the boy on the box if the velocity change to 1.0 ms?
The work done is zero because the velocity is constant. Work is only done when there is a change in velocity.
When is an object said to have uniform velocity?
An object is said to have uniform velocity when it is moving in a straight line and covers equal distances in equal time intervals. This means the object's speed remains constant and there is no change in its direction of motion.

A force of 80.0 N is required to pull a 25.0kg block across a constant velocity on a smooth surface on earth What force is required to pull the same block across the surface of Jupiter?
That's a trick question, right? Jupiter has no surface.
A science book is being pushed across a table Can the book have a constant speed and a changing velocity?
It can have a constant speed, and a changing velocity, but it cannot have the two at the same time. Remember: Velocity = speed with a directional component.
How will the velocity of the book change as it moves across the surface with friction?
The velocity of the book will decrease as it moves across the surface with friction. Friction acts in the opposite direction of motion, slowing down the book.
What is the first law of motion to the motion of an ice skater sliding across the ice st a constant velocity?
The first law of motion, also known as the law of inertia, states that an object at rest will stay at rest, and an object in motion will stay in motion at a constant velocity unless acted upon by an external force. In the case of an ice skater sliding across the ice at a constant velocity, the skater will continue moving at that constant velocity unless a force (like friction or wind resistance) acts to change their motion.

As a block slides across a horizontal surface with constant velocity describe the changes of the energy that would occur within the block.?
As the block slides with constant velocity, its kinetic energy remains constant. The work done by friction converts some of this energy into heat, resulting in a decrease in the block's internal energy. Overall, the total mechanical energy (sum of kinetic and potential energy) of the block does not change.
If you push a chair across the floor at a constant velocity how does the force of friction compare with the force?
If the chair is moving at a constant velocity, the force of friction is equal and opposite to the force you are exerting on the chair. This is to maintain the equilibrium of forces acting on the chair.
Force that opposes motion of surface as it moves across another surface?
the force that opposes the motion of two touching surfaces is velocity.
A glider sailing across the sky at a steady speed and altitude an example of and unbalanced force?
No, a glider sailing across the sky at a steady speed and altitude is an example of a balanced force. The force of gravity pulling the glider down is balanced by the lift generated by the glider's wings, allowing it to maintain its steady speed and altitude.
