Which has more thermal energy? If two objects made of the same substance have different masses or temperatures, you can determine which has more thermal energy. If the objects have different masses but are otherwise the same, the one with more mass has more thermal energy. What is thermal power in short? Thermal power describes […]
Is there another way of writing a very big or small numbers?
Is there another way of writing a very big or small numbers? Scientific notation is a way of writing very large or very small numbers. A number is written in scientific notation when a number between 1 and 10 is multiplied by a power of 10. For example, 650,000,000 can be written in scientific notation […]
Can a body have zero velocity and still be accelerating?
Can a body have zero velocity and still be accelerating? Yes, an object can have zero velocity and still be accelerating simultaneously. Then the object will start to move in the backward direction. Is acceleration zero at the turn around point? 4. Acceleration is always smaller then velocity. A point where an object reverses its […]

Can you cut and splice O2 sensor wires?
What is natural frequency and resonance?
What is natural frequency and resonance? The natural frequency is the frequency at which an object will remain vibrating after hitting it. What happens when you excite that object at the same frequency as its natural frequency? Well, that is resonance. What is the difference between frequency and fundamental frequency? The fundamental frequency is just […]
Is it dangerous to connect two extension cords?
Is it dangerous to connect two extension cords? If you plug two identical cords into each other, that reduces their current capacity in half and can possibly result in voltage drop and overheating. In general, extension cords should not exceed 100 feet in length. However, by plugging one extension cord into another, the maximum cord […]
Why do we need to study dynamics?
Why do we need to study dynamics? As a field of study it is very important for analyzing systems consisting of single bodies or multiple bodies interacting with each other. A dynamics analysis is what allows one to predict the motion of an object or objects, under the influence of different forces, such as gravity […]
What causes capillarity and surface tension?
What causes capillarity and surface tension? Adhesion of water to the walls of a vessel will cause an upward force on the liquid at the edges and result in a meniscus which turns upward. The surface tension acts to hold the surface intact. Capillary action occurs when the adhesion to the walls is stronger than […]
