Forces with Constant Velocities: Formulas & More

In summary, a force with constant velocity is a force that causes an object to move at a constant speed in a specified direction. The formula for this force is F = m x a, where F is the force, m is the mass of the object, and a is the acceleration. Examples of forces with constant velocity include gravity, friction, and air resistance. Constant velocity differs from constant acceleration in that the former refers to constant speed while the latter refers to a change in velocity over time. There is a direct relationship between force and velocity, with an increase in force resulting in an increase in velocity, described by the formula F = m x a.

I was wondering why can't I use formulas from the "Special Relativity" in cases like:
F=mv^2/r Or F=qv•B
I understeand that in the F=mv^2/r the velicity isn't constat,it changes with the vector,are there any other formulas?

Special relativity relates observations between inertial reference frames.
The presence of an unbalanced force indicates a non-inertial reference frame.
Another, famous, example is gravitation.

There are techniques for handling accelerations in special relativity - you'll get to those later.

1. What is a force with constant velocity?

A force with constant velocity is a force that acts on an object and causes it to move at a constant speed in a specified direction.

2. How is the force with constant velocity formula calculated?

The formula for force with constant velocity is F = m x a, where F is the force, m is the mass of the object, and a is the acceleration. This formula is based on Newton's second law of motion.

3. What are some examples of forces with constant velocity?

Some examples of forces with constant velocity include gravity, friction, and air resistance. These forces act on objects at a constant rate and can affect their movement.

4. How does constant velocity differ from constant acceleration?

Constant velocity refers to an object moving at a constant speed in a specified direction, while constant acceleration refers to an object changing its velocity at a constant rate over time.

5. What is the relationship between force and velocity?

Force and velocity are directly proportional, meaning that as force increases, velocity also increases. This relationship is described by the formula F = m x a, where m is the mass of the object and a is the acceleration.
