Physics teacher | Tutor for 10 years

I hold a degree in Physics from New Mexico Tech. With a passion for unraveling the mysteries of the universe, I thrive on sharing my knowledge with curious minds. Through interactive sessions, I simplify complex concepts, making physics accessible and engaging for students. Whether it's classical mechanics or quantum theory, I foster a supportive environment where questions are encouraged and critical thinking flourishes. My goal is to inspire a lifelong love of learning and empower students to explore the wonders of science. Let's embark on a journey of discovery together!

## Questions

Why are standardized units of measurement important?

What is the difference between the 1st and 2nd law of thermodynamics?

A charge of #2 C# is at the origin. How much energy would be applied to or released from a # 1 C# charge if it is moved from # ( -4, 0 ) # to #( 2 , 4 ) #?

A projectile is shot from the ground at an angle of #pi/4 # and a speed of #16 m/s#. Factoring in both horizontal and vertical movement, what will the projectile's distance from the starting point be when it reaches its maximum height?

It is question about forces and equilibrium ?

An object with a mass of #5 kg# is hanging from an axle with a radius of #18 m#. If the wheel attached to the axle has a radius of #6 m#, how much force must be applied to the wheel to keep the object from falling?

An object, previously at rest, slides #5 m# down a ramp, with an incline of #pi/3 #, and then slides horizontally on the floor for another #2 m#. If the ramp and floor are made of the same material, what is the material's kinetic friction coefficient?

The latent heat of fusion of water is 334 J/g. How much energy is released when 20 grams of water at 0°C undergoes freezing?

A projectile is shot at an angle of #pi/3 # and a velocity of # 24 m/s#. How far away will the projectile land?

If a #5 kg# object moving at #2 m/s# slows to a halt after moving #50 m#, what is the coefficient of kinetic friction of the surface that the object was moving over?

What is the electric current produced when a voltage of #9 V# is applied to a circuit with a resistance of #36 Omega#?

An object with a mass of #8 kg# is on a plane with an incline of # - pi/3 #. If it takes #15 N# to start pushing the object down the plane and #12 N# to keep pushing it, what are the coefficients of static and kinetic friction?

If an object is moving at #4 ms^-1# over a surface with a kinetic friction coefficient of #u_k=3 /g#, how far will the object continue to move?

What is the relative velocity equation?

The electric field intensity at P and Q in the shown arrangement are in the ratio???

What are the differences between isothermal expansion and adiabatic expansion?

A model train with a mass of #4 kg# is moving along a track at #6 (cm)/s#. If the curvature of the track changes from a radius of #32 cm# to #45 cm#, by how much must the centripetal force applied by the tracks change?

How is acceleration due to gravity calculated?

An object's two dimensional velocity is given by #v(t) = ( t^2 +2 , cospit - 3t )#. What is the object's rate and direction of acceleration at #t=1 #?

What is the cross product of #[1, -2, -3]# and #[1, 3, 4]#?
