What do you mean by critical velocity by method of dimensions establish its relation?
Critical velocity is the minimum velocity required for an object to overcome a particular resistance force. By using the method of dimensions, you can establish a relationship between critical velocity and the factors that influence it, such as the viscosity of the fluid, density of the fluid, and the size and shape of the object. By analyzing the dimensions of these factors and the force equation, you can derive an equation that relates critical velocity to these variables.
What are the dimensions of angular velocity in terms of its physical units?
Angular velocity is a measure of how quickly an object rotates around a fixed point. Its dimensions are typically expressed in units of radians per second (rad/s) or degrees per second (/s).
What is the motion of objects moving in two dimensions under the influence of gravity a. horizontal velocity b. directrix c. vertical velocity d. projectile motion?
horizontal velocity
Is velocity the same as acceleration?
No, velocity and acceleration are not the same. Velocity is the rate of change of an object's position with respect to time, while acceleration is the rate of change of an object's velocity with respect to time. In other words, acceleration measures how quickly an object's velocity is changing.
What are the key dimensions of momentum and how do they influence the motion of an object?
The key dimensions of momentum are mass and velocity. Momentum is the product of an object's mass and its velocity. The greater the mass or velocity of an object, the greater its momentum. Momentum influences the motion of an object by determining how difficult it is to stop or change the object's direction. Objects with higher momentum are harder to stop or change their course compared to objects with lower momentum.

How are acceleration and speed alike?
They are not alike but they are related. A positive acceleration means an increase in velocity (speed). A negative acceleration means a decrease in velocity. Velocity (speed) has the dimensions of distance / time. Acceleration has the dimensions of distance/time2 or velocity/time.
What are the dimensions of a pitching wedge for golf?
velocity distends and altotoot
What 2 things must you know to descriobe the motion of an object?
If movement is in two dimensions: the x-coordinate of the velocity, and the y-coordinate of the velocity. Or alternatively: the magnitude of the velocity, and the direction. If movement is in three dimensions, you need to know three things, for example, x-coordinate, y-coordinate, and z-coordinate of the velocity, or magnitude of the velocity and two components of direction.
What is the homogeneity of v2 equals u2 plus 2as?
Each term in the equation has dimensions of velocity-squared (remember "a" here is acceleration which is velocity divided by time, so "as" is velocity x distance / time = velocity squared).

How would you differentiate speed time distance and velocity?
Velocity is a vector: it has a direction. The others are all scalars. The dimensions of the scalars are Speed : [LT-1] Time: [T] Distance: [L]

Objects with higher momentum are harder to stop or change their course compared to objects with lower momentum.
If energy (E) velocity (v) and force(F) be taken as fundamental quantity then what are the dimensions of mass?
If energy, velocity, and force are taken as fundamental quantities, we can express mass in terms of these fundamental quantities using dimensional analysis. The dimensions of mass in this system would be [M] = [E] * [v]^2 / [F].
Does dimensions mean area?
No, it does not. Dimensions are the basic quantities which are being measured. The most common are [L] for length, [M] for mass and [T] for time. Speed and velocity are [LT^-1] Force is [MLT^-2].
