Help with motion, electricity, magnetism and light in physics for electronics.
Ask if we can help
Course overview
PHY354 covers physics for electronics in Seneca’s Electronics Engineering Technology program. Its published scope includes Newtonian, rotational and harmonic motion, electricity, magnetism and light. The worked example below uses a spring oscillator to connect motion and energy. Your current chapter will help us choose the physical model to work on with you.
PHY354 topics to review
Newtonian and rotational motionHarmonic motionElectricity, magnetism and light
Common difficulties
- Equating maximum displacement with maximum speed
- Using a formula without its model assumptions
Useful foundations to review
Review force diagrams, energy units and trigonometric functions. In oscillations, distinguish amplitude, angular frequency and speed. For electric or magnetic questions, identify which quantities are vectors before adding them.

Check the official course catalogueFind the maximum speed of an ideal spring oscillator
A 0.50 kg mass oscillates on a horizontal spring with stiffness 200 N/m. Its amplitude is 0.10 m. Ignore friction. Find its angular frequency and maximum speed.
Show the reasoning
Choose the ideal oscillator model
Here is the mass, the spring stiffness and the amplitude. For a mass on an ideal spring, . This is angular frequency, not 20 cycles per second.
Locate and calculate the maximum speed
The maximum speed is . It occurs at equilibrium, where the displacement is zero. At the turning points the speed is zero.
Check by conservation of energy
At a turning point, energy is . At equilibrium it is . Energy transfers between spring potential and kinetic forms.
Try a changed problem
If the amplitude doubles but mass and stiffness stay fixed, how do angular frequency, maximum speed and total energy change?
Check your reasoning
Angular frequency stays 20 rad/s. Maximum speed doubles to 4.0 m/s. Total energy quadruples to 4.0 J because it depends on amplitude squared.
How tutoring can help
A tutor can help you turn the wording of a problem into a sketch, choose a physical model and work through the calculation step by step. For oscillations, you can compare turning points with equilibrium and use energy to check a speed. You can ask for help from the first step or review work you’ve already tried.
Exam preparation for PHY354
Sort practice by the physical principle required, then mix the questions. State idealizations such as negligible damping before using conservation. Include a verbal explanation of where the system is fastest and where its stored potential energy is greatest.
Use your section’s outline to choose the chapters to review. We work through permitted practice and comparable problems, without completing graded assignments or exams on your behalf.
