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 pulling across a level surface at a constant velocity what force is the pulling force equal to?
When an object is moving across a level surface at a constant velocity, the pulling force is equal to the force of friction acting in the opposite direction. This force of friction is equal in magnitude and opposite in direction to the pulling force, resulting in a balanced situation where there is 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.
You are pushing a kg wooden crate across the floor. the force of sliding friction on the crate is 90 N. how much force must you exert on the crate to keep it moving with a constant velocity?
To keep the crate moving with constant velocity, the force you exert must balance the force of sliding friction. In this case, you must exert a force of 90 N in the opposite direction of the sliding friction, so the net force on the crate is zero and it remains in motion at a constant velocity.
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.

A force of 320 N is required to pull a box across the floor at a constant velocity What is the force of friction between the floor and the box?
It's 320 N. Since the friction force is in the direction opposite to the motion, thepulling force and the friction force balance, the net horizontal force on the box iszero, and its speed is therefore constant.
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.
What force is needed to slide a 250-kg crate across the floor at constant velocity if the coefficient of sliding friction between a crate and a horizontal floor is 0.25?
The force needed to slide the crate at constant velocity is equal in magnitude but opposite in direction to the force of friction. The force of friction can be calculated as the product of the coefficient of friction and the normal force acting on the crate (weight of the crate). Therefore, the force needed would be 250 kg * 9.8 m/s^2 * 0.25 = 612.5 N.
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.
Can A hockey puck that slides across the ice at a constant speed be in equilibrium?
Yes, a hockey puck sliding across the ice at a constant speed can be considered to be in dynamic equilibrium. While the puck is moving, the forces acting on it are balanced, resulting in no acceleration in its velocity.
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.
A man pushes a large box across a rough wooden floor. The box moves with constant velocity. What can be said about the forces acting on the box?
There is no unbalanced force acting on the box.
