If you push a crate at constant velocity how do you know how much friction acts on the crate compared to your pushing force?
When an object moves at a constant velocity, all forces acting on it must add up to zero.
In the case of the crate on a horizontal surface, where the pushing force is directly horizontal (not down and horizontal), then the human push force must be equal and opposite to the friction force.
In the case where the plane is inclined and/or where the human force isn't directly along the surface, we need to know the angles, component-ize all forces (human push force, normal force, friction, and weight), balance forces in the direction perpendicular to the plane (so it will not sink through the plane), and balance forces parallel to the plane (if it is to move at a constant velocity).
What else can I help you with?
If we push a crate at a constant velocity how do we know how much friction acts on the crate compared to our pushing force?
If the crate is moving at a constant velocity, then the force of friction acting on the crate is equal in magnitude and opposite in direction to the force you are applying to push the crate. This means that the force you apply to push the crate is balancing out the force of friction acting against it. By measuring the force you are exerting and observing the constant velocity of the crate, you can infer the magnitude of the friction force.
If you push horizontally on your book with a force of 1 N to make the book slide at constant velocity how much is the force of friction on the book?
The force of friction would also be 1 N, equal in magnitude but opposite in direction to the force you are pushing with. This equal and opposite force of friction is what allows the book to move at a constant velocity.
If you push a crate with a force of 100 N and it slides at a constant velocity how much is the friction acting on the crate?
If the crate is moving at a constant velocity, the friction force is equal in magnitude but opposite in direction to the pushing force, so it is also 100 N. This is because the two forces are balanced and there is no net force acting on the crate.
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.
Once the crate is sliding how hard do you push to keep is moving at constant valocity?
You should push with a force equal to the force of friction acting on the crate. This will counteract the friction force and allow the crate to continue moving at a constant velocity. Pushing with a greater force will accelerate the crate, while pushing with a force lower than the frictional force will cause it to decelerate.
If an object has a natural tendency to move with constant velocity why do you need to keep pushing a cabinet to move it with constant velocity?
If the cabinet is on a floor, it is being acted upon by earth's gravity and friction with the floor. Newton's law says an object in motion will continue in motion unless acted upon by another force. Consider the outside forces acting on the cabinet. They are acting on the cabinet to slow it down, and you need to keep pushing it to overcome them and keep the cabinet moving.
If a car is traveling on the highway at a constant velocity the force that pushes the car forward must be?
1. force that moves a car forward is the friction force between the tires and the road (ignoring what is going on mechanically in the car) 2. if the car is travelling at constant velocity, net force is zero - forces pushing car forward are equal to forces pushing car back
What magnitude pushing force is needed to keep a box moving at a constant 8 meter per sec if there is a static friction of 5 lb and kinetic friction of 4 lb?
While the box is moving in a straight line at a constant speed, the push only has to overcome the kinetic friction. Whatever the speed is, and whatever the weight of the box is, 4 pounds of push IN THE DIRECTION THE BOX IS MOVING will keep this one going.
How is an able to maintain a constant speed when friction acts upon it?
An object maintains a constant velocity when the net force acting upon that object is zero. Therefore, a force pushing against the object that exactly opposes the force(s) due to friction (in both magnitude and direction) will result in a net force of zero, and the object will maintain a constant speed.
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.
What is required for an automobile to travel at a constant velocity?
For an automobile to travel at a constant velocity, the net force acting on the car needs to be zero. This means the forces pushing the car forward (engine power) must be balanced by the forces resisting its motion (friction, air resistance). Additionally, the car must maintain a balanced speed and direction without any external influence.
What two Forces Have to Be equally strong in order for a falling object to reach terminal velocity?
The force of gravity pulling the object downward must be equal to the force of air resistance pushing upward on the object. When these two forces are balanced, the object stops accelerating and reaches terminal velocity, where its speed remains constant.
