When an object reaches its terminal velocity, it can no longer accelerate, so its acceleration becomes zero, and it falls at a constant speed. As an object falls freely through the air, it has two forces acting upon it: gravity and drag.
Every object has a terminal velocity, which is the speed it can travel while having a constant force. When an object falls it typically accelerates as it falls, however, eventually the air resistance or drag becomes too great to allow the object to continue accelerating. This occurs when the gravitational force and drag become equal. If an object is falling under a source of power other than gravity, such as an engine, then it will take longer for it to reach its terminal velocity.Learn More
Acceleration is a vector quantity, which means that it has both a direction and a magnitude. Acceleration is the rate at which the velocity of an object changes. Velocity is also a vector and also has a direction.Full Answer >
A gyroscope sensor is a sensor on a mobile phone that tracks rotation or twist. The gyroscope is one of several sensors on a mobile phone that includes an accelerometer, a barometer and a compass.Full Answer >
The work output of a machine divided by the work input is the efficiency of the machine. Efficiency is typically stated as a percentage and is calculated by dividing work output by input and then multiplying by 100.Full Answer >
Friction makes the observation of Newton's first law difficult because it is an unseen force that interferes with the law. Newton's first law states that an object in motion continues its motion unless acted on by an unbalanced force. Friction is a contact force that opposes motion; an object in motion in a real-world scenario eventually slows down due to friction, even though it seems to slow down by itself.Full Answer >
