An object starts at rest and accelerates to a high speed. Which of the following properties does not change?
a- mass
b-kinetic energy
c- length
d- electric charge
Electric charge is invariant, i.e it is independent of speed of the particle. In contrast to mass and energy of particle which varies with speed of particle (relativistic mass and energy), charge remains the same.
Length also varies with speed.
(d) is the correct answer.

A proton is released from rest at point A in a constant electric field and accelerates to point B (see part a of the drawing). An electron is released from rest at point 8 and accelerates to point A (see part b of the drawing). How does the change in the proton's electric potential energy compare with the change in the electrons electric potential energy? O The proton experiences a greater change in electric potential energy, since it has a...
An object of mass m moving at speed v0 strikes an object of mass 2 m which had been at rest. The first object bounces backward along its initial path at speed v 0. Is this collision elastic, and if not, what is the change in kinetic energy of the system? a) The kinetic energy decreases by mv^2. b) The kinetic energy increases by mv^2. c) The kinetic energy decreases by mv^2/2. d) The collision is elastic.
An EV starts at rest at position A and ends its travel at position C as shown in the following figure. The EV starts at zero speed at A and accelerates uniformly over time and reaches to 80 mile/hour at point B From point B to C it starts with 80 mile/hour and accelerates uniformly over time during this period and reaches 100 mile/hour at point C. The vehicle has the following parameter values: m-700 kg, CD-0.2, AF 2.1 m2,...
