Which force best represents FG a weight lifter is pushing a barbell upward with a force of 90 N the weight of a barbell acting on a weight lifter is 80 n the amount of upward force of a table on a box is 25 n a box on a rough table has difficulty sliding?
The correct option is (B). Option (1) : A weight lifter is pushing a barbell upward with a force of 90 N. It represent the applied force. Option (2) : The weight of a barbell acting on a weight lifter is 80 N. It represent the gravitational force .
Which notation is commonly used on a force diagram to show forces acting on an object?
The notation that are commonly used on force diagrams to show forces acting on an object are put marked, check image. These are force is z-direction, Force due to gravity, Frictional force.
Which refers to the sum of all the forces that act upon an object?
The net force is the vector sum of all the forces that act upon an object.
Which factor may result from an unbalanced force?
Unbalanced forces are not equal, and they always cause the motion of an object to change the speed and/or direction that it is moving. When two unbalanced forces are exerted in opposite directions, their combined force is equal to the difference between the two forces.
What is the best example of forces acting in the same direction?
Explanation: Because it asks what is the best example of forces acting in the SAME direction, it will be two football players pushing a tackling sled. This means, since the two football players are both pushing the sled, they will also be pushing it at the same time in the same direction./span>
Which best describes parallel forces?
Answer. The explanation: -when the parallel force system is a situation in which two forces of equal magnitude act in the same direction within the same plane, Two forces that are parallel can either be in the same direction or in opposite directions./span>
Which best describes a force a vector with magnitude and direction?
Answer. Answer: a direction vector with speed and strength./span>
Which represents the upward force perpendicular to the floor?
normal reaction force
Which best describe a force?
Answer: a vector with magnitude and direction..
Which piece of furniture will have the most inertia?
Answer. It is obvious that the 75 kg dining table will be very difficult to move because it has the more inertia. The 75 Kg dining table has more weight so that it will be required more inertia./span>
Which prediction will most likely describe how friction will affect her findings?
Which prediction will most likely describe how friction will affect her findings? The distance for Trial 3 will be greater than the distance for Trial 4 because the difference in surface roughness will affect friction.
When a cabinet touches the floor which type of force exists?
When you move a chair across the floor what force must push be stronger than?
The force you exerted in pushing the chair must be stronger that the resisting force and weight of the chair in order for it to move..
What kind of force is a push?
Contact forces involve push, pull and friction. A contact pull and friction. A contact force is when two interacting objects are physically touching, for example: when you are throwing a ba throwing a ball you are using a contact force.
