Why clockwise torque is negetive?
In the context of physics and engineering, the convention is that counterclockwise torque is considered positive and clockwise torque is considered negative. This convention simplifies calculations and allows for a consistent understanding of rotational motion. It is purely a matter of convention and does not affect the physical behavior of the system.
Why is anti-clockwise torque positive?
Anti-clockwise torque is considered positive because it causes an object to rotate in the counter-clockwise direction. In physics, the convention is to assign a positive value to any torque that tends to cause a counterclockwise rotation and a negative value to any torque that tends to cause a clockwise rotation. This convention allows for consistency in calculating and analyzing rotational motion.
Is displacement considered positive or negative in the context of physics?
In physics, displacement can be either positive or negative depending on the direction of the movement. Positive displacement indicates movement in one direction, while negative displacement indicates movement in the opposite direction.
How can the concept of work be negative in the context of physics?
In physics, work is considered negative when the force applied to an object is in the opposite direction of the object's displacement. This means that the force is doing work against the motion of the object, resulting in a negative value for the work done.
In physics what is the law of moments?
An object is in equilibrium when the net force and the net torque on it are zero. to add Moment = Force X Perpendicular distance from pivot. Definition :- it states that the moment of force about an axes is equal to the sum of moments about same axes.

When is work negative in physics and how does it affect the overall energy of a system?
Work is considered negative in physics when the force applied is in the opposite direction of the displacement. This means that energy is being taken away from the system rather than added to it. As a result, the overall energy of the system decreases when negative work is done.
Downward velocity is considered a negative. true or false?
Downward velocity is considered a negative. This is a true statement.
What do mean physics?
Physics is a type of Science such as biology and chemistry. Physics is the most math based Science. It can involve anything from gravity to moments (turning force).
Is it possible for velocity to be negative in physics?
Yes, velocity can be negative in physics when an object is moving in the opposite direction of the chosen positive direction.
Can work positive or Negative in physics how?
Yes Work can be positive or Negative.
What are the other divisions of physics?
The phrase "other divisions" implies that you already have some division or divisions in mind. But you have chosen not to share that information. So it is not possible to tell whether you know of just one division of physics and want a list of the rest or if you know of 20 and want the remainder. Furthermore, any division, such as mechanics, can be considered a single division of physics or it can be considered as consisting of divisions such as statics, dynamics, moments and so forth.
What directions usually considered positive or negative?
In mathematics and physics, directions are often categorized as positive or negative based on a defined reference frame. For instance, on a number line, movements to the right are typically considered positive, while movements to the left are negative. In the Cartesian coordinate system, movement upwards (in the y-direction) is positive, whereas movement downwards is negative. Similarly, in a three-dimensional space, movement away from the origin can be considered positive, while movement towards it is negative.
