How do machines help us in everyday life? Simple machines make the things in everyday life work. These simple machines are used in more complex devices every day, making tasks much easier. Simple Machines. Simple machines make tasks simpler by reducing the amount of effort it takes for humans to perform certain tasks. What are […]

What is a low center of gravity? The lower your center of gravity, the easier it is to keep your balance. If you’re sitting on a chair, you can lean over more than if you’re standing up. With your center of gravity low, you can lean further to one side or the other without creating […]

What are the 5 types of data? Common data types include: Integer. Floating-point number. Character. String. Boolean. What are examples of data types? Common examples of data types Boolean (e.g., True or False) Character (e.g., a) Date (e.g., 03/01/2016) Double (e.g., 1.79769313486232E308) Floating-point number (e.g., 1.234) Integer (e.g., 1234) Long (e.g., 123456789) Short (e.g., 0) […]

What is the variable you change? An easy way to think of independent and dependent variables is, when you’re conducting an experiment, the independent variable is what you change, and the dependent variable is what changes because of that. You can also think of the independent variable as the cause and the dependent variable as […]

What is the electric potential if the electric field is zero? If the electric field is zero, then the potential has no gradient i.e.: the potential is equal across space. But potential is always measured relative to a baseline, so it can therefore be considered as zero. Can electric potential at a point be zero […]

What is the uncertainty in the mass of a muon? muon mass Standard uncertainty 0.000 000 042 x 10-28 kg Relative standard uncertainty 2.2 x 10-8 Concise form 1.883 531 627(42) x 10-28 kg Click here for correlation coefficient of this constant with other constants What is produced when a muon decays? The muon is […]

Is walking a push or pull? Take walking. We walk by pushing down and backwards on the ground. The ground, obedient slave to the laws of physics that it is, pushes up and forwards on our feet, propelling us along. How do you know that a push or a pull is a force? All forces […]

What happens when we press accelerator? When you step on the gas pedal you initiate a process that delivers air and fuel to the engine. As the gas pedal is pressed, it turns a pivot that in turn pulls the throttle wire. The throttle wire is connected to a throttle linkage. That linkage serves to […]
