Acceleration is not in direction of force

In summary, the conversation is discussing the relationship between acceleration and force. It is mentioned that acceleration is not always in the direction of force, specifically when considering the equation dp/dt=m\gamma^3[a+vX(vXa)]. There is also a mention of a previous thread being locked to avoid further discussion, and a correction is made regarding the direction of acceleration in relation to motion.

"acceleration is not in direction of force"

The following quote was in a post now closed:
"i don't know how this person says that acceleration is not in direction of force
there fore angle HAS to be zero degrees."
If "force" is meant to be dp/dt, then "acceleration is not in direction of force."
Since dp/dt=m\gamma^3[a+vX(vXa)], there are important cases where
"acceleration is not in direction of force."

Meir, when a thread has been locked, it defeats the purpose of locking it, if a new thread starts off on attempting to dispute something that was said in the earlier thread. A continuation of the discussion is specifically what the moderating mentors wanted to avoid.

Err..Sorry it was me who typed that.I meant to say isn't acceleration in the direction of motion.Sorry my mistake
 

1. What is acceleration not being in the direction of force?

Acceleration not being in the direction of force means that an object's acceleration is not directly proportional to the direction of the force acting on it. In other words, the direction of the force does not determine the direction of the acceleration.

2. How does this concept differ from Newton's Second Law of Motion?

Newton's Second Law of Motion states that the acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass. This means that the direction of the force does play a role in determining the direction of the object's acceleration. However, acceleration not being in the direction of force is a concept that applies in certain situations where the force acting on the object is not the net force.

3. Can you provide an example of acceleration not being in the direction of force?

One example of this is when a car is driving around a circular track. The force of friction between the tires and the road provides the centripetal force needed to keep the car moving in a circle. However, the acceleration of the car is directed towards the center of the circle, not in the direction of the force of friction.

4. How does this concept impact our understanding of motion?

Understanding that acceleration is not always in the direction of force allows us to better explain and predict the motion of objects in certain scenarios. It also helps us to understand how different forces acting on an object can affect its acceleration in different ways.

5. Are there any real-world applications of this concept?

Yes, this concept is important in fields such as physics and engineering when designing and analyzing systems that involve circular motion or multiple forces acting on an object. It is also relevant in sports and athletics, such as understanding the motion of a discus throw or a gymnast on the uneven bars.
