Two cars travel in the same direction. car #1 travels at 50 mph, car #2 travels at 75 mph and passes car #1. The relative velocity of car #2 from car #1's perspective is 25 mph.
More Information:
This means that if car #2 crashed into the back of car #1, the collision would be the same as if car #1 was parked and car #2 crashed into the back of it at 25 mph.

What is the equation for relativistic mass in terms of velocity and the speed of light?
The equation for relativistic mass in terms of velocity (v) and the speed of light (c) is: m m0 / (1 - v2/c2) where m is the relativistic mass, m0 is the rest mass, v is the velocity, and c is the speed of light.
What is the formula for calculating the non-relativistic kinetic energy of an object?
The formula for calculating the non-relativistic kinetic energy of an object is KE 1/2 m v2, where KE is the kinetic energy, m is the mass of the object, and v is the velocity of the object.
What is the amount of work required to accelerate relativistic particles?
The amount of work required to accelerate relativistic particles is determined by their mass and the speed at which they are accelerated. This work is calculated using the formula W (1/2)mv2, where W is the work, m is the mass of the particle, and v is the velocity at which it is accelerated.
What is the relativistic mass formula and how does it relate to the concept of mass in special relativity?
The relativistic mass formula is given by (m fracm0sqrt1 - fracv2c2), where (m) is the relativistic mass, (m0) is the rest mass, (v) is the velocity of the object, and (c) is the speed of light. This formula shows that as an object moves faster, its relativistic mass increases due to the effects of special relativity. This concept challenges the traditional idea of mass as a constant property of an object and demonstrates that mass is relative to an observer's frame of reference in special relativity.
What are the key differences between relativistic and non-relativistic physics?
Relativistic physics considers the effects of high speeds and strong gravitational fields, while non-relativistic physics does not. Relativistic physics incorporates Einstein's theory of relativity, which shows that time and space are relative and can be affected by motion and gravity. Non-relativistic physics, on the other hand, is based on classical mechanics and does not take into account these relativistic effects.

Is emc2 correct?
It is not the entire equation, but for current practical purposes, it is correct. If an object is moving at relativistic speeds, it is not correct. It requires you use relativistic mass, which is based on the velocity relative to the speed of light. It is correct for any human purposes.
What is the formula for calculating the non-relativistic kinetic energy of an object?
The formula for calculating the non-relativistic kinetic energy of an object is KE 1/2 m v2, where KE is the kinetic energy, m is the mass of the object, and v is the velocity of the object.
What fraction of the speed of light must you travel for your mass to be twice the rest mass?
To have a mass that is twice the rest mass at relativistic speeds, you would need to travel at about 86.6% of the speed of light. This is calculated using the relativistic mass formula, which states that mass increases with velocity according to the equation: m = m0 / sqrt(1-v^2/c^2), where m is the relativistic mass, m0 is the rest mass, v is the velocity, and c is the speed of light.

What is the equation for velocity approaching that the speed of light?
The equation for velocity approaching the speed of light is given by the relativistic velocity addition formula: v = (u + v') / (1 + u*v'/c^2), where v is the relative velocity between two objects, u is the velocity of the first object, v' is the velocity of the second object, and c is the speed of light in a vacuum.

Non-relativistic physics, on the other hand, is based on classical mechanics and does not take into account these relativistic effects.
What is the significance of 4-velocity in the context of special relativity?
In the context of special relativity, 4-velocity is significant because it describes an object's movement through both space and time. It is a four-dimensional vector that combines the object's regular velocity with its time component, providing a comprehensive understanding of its motion in a relativistic framework.
What is the derivation of relativistic momentum and how does it differ from classical momentum?
The relativistic momentum is derived from Einstein's theory of special relativity, which takes into account the effects of high speeds and near-light velocities. It differs from classical momentum in that it includes a factor of gamma () to account for the increase in mass as an object approaches the speed of light. This means that as an object's velocity increases, its relativistic momentum also increases, unlike classical momentum which remains constant at all speeds.
What are the two parts of kinetic energy?
The non-relativistic equation for kinetic energy is mv^2/2 where mass is m and velocity is v. The relativistic kinetic energy equation is m/(1-(v^2/c^2))-m where m is mass, v is velocity and c is the speed of light. The two variables which determine the kinetic energy of an object are mass and velocity.
What will be the path of moving clock if its velocity is comparable to velocity of light?
If the velocity of the moving clock is comparable to the speed of light, it will experience time dilation, length contraction, and relativistic effects according to the theory of special relativity. The path of the clock will be distorted from the perspective of a stationary observer, and its time measurements will differ significantly from those made by a stationary clock.
