    Sum Tan
In summary, the conversation discusses the calculation of the sum of tangential acceleration and radial acceleration in circular motion. The total acceleration is the vector sum of these two orthogonal components, and it represents the rate of change of velocity. The components are given in terms of perpendicular and tangent directions for conceptual ease.

Today I was doing a homework that asked me to calculate the sum of some particular tangential acceleration and radial acceleration in a circular motion.

We all know clearly about the concepts independently, but I wonder what the physical meaning the sum of the two accelerations is? Or it is just a some kinda tool like math?

Thanks for reading

Presumably they want the vector sum of those two orthogonal components, which gives you the total acceleration of the body.
 
  • #3
so what is the physical meaning of the total acceleration?
Is it something produced by the two accelerations' definitions?
 
  • #4
It's the rate of change of velocity. Just the plain old regular acceleration that you've hopefully learned about before...

Basically, any particle undergoing a curved path has an acceleration (which is what allows it to curve) - the components of the acceleration could have been taken in any direction not orthogonal to the acceleration, but since we have a conceptual basis of perpendicular to the path and tangent to the path, its easier to give the components in terms of those directions.

FAQ: What is the meaning of the sum of tan A and rad A?

What is the meaning of the sum of tan A and rad A?

The sum of tan A and rad A is a mathematical expression that represents the sum of the tangent of an angle (A) and the radian measure of that same angle (A). It is a common operation in trigonometry and calculus.

What is the formula for calculating the sum of tan A and rad A?

The formula for calculating the sum of tan A and rad A is tan A + rad A. The tangent of an angle can be calculated using a scientific calculator or by using the formula tan A = opposite/adjacent. The radian measure of an angle can be found by dividing the angle in degrees by 180 and then multiplying by π (pi).

What does the sum of tan A and rad A represent in real-life situations?

The sum of tan A and rad A can represent various real-life situations, such as calculating the height of a tree using its shadow and the angle of the sun's rays, determining the slope of a roof or hill, or calculating the velocity of a moving object.

What happens when the value of tan A and rad A are equal?

If the value of tan A and rad A are equal, then the sum of the two will be twice the value of either one. This is because the tangent of an angle is equal to the radian measure of that angle divided by 180 multiplied by π (tan A = rad A/180π).

Can the sum of tan A and rad A be negative?

Yes, the sum of tan A and rad A can be negative. This can occur when the tangent of an angle is negative and the radian measure of that same angle is positive, or vice versa. In fact, the sum can be positive, negative, or zero depending on the values of tan A and rad A.
