When you talk about speed, the direction is irrelevant (scalar quantity); when you talk about velocity, the direction is of interest (vector quantity). Therefore, the speed is 8 ft/sec., and the velocity is 8 ft/second in a downward direction.
Its speed is 6 feet per second. Its velocity is 6 feet per second in whatever direction it's going.
During auto-rotation, a helicopter's main rotor generates lift from the relative wind passing over the blades as the helicopter descends. If the helicopter dives too steeply during auto-rotation, the increased airspeed can cause the rotor blades to stall, reducing lift and potentially allowing the helicopter to reach terminal velocity. At terminal velocity, the forces of gravity and air resistance are balanced, leading to a constant descent speed.
The weight of the helicopter affects the terminal speed by influencing the rate at which the helicopter falls. A heavier helicopter will reach a higher terminal velocity compared to a lighter helicopter, as the force of gravity will be greater on the heavier helicopter, causing it to accelerate faster. Additionally, a heavier helicopter may require more lift to counteract its weight, which can also impact its terminal speed.
Velocity(speed).
increase- your speed will increase until terminal velocity is reached. From there it will stay constant.
The SI unit for speed and velocity is meters per second (m/s). Speed is a scalar quantity that represents how fast an object is moving, while velocity is a vector quantity that includes both speed and direction.
Velocity is speed and its direction. The units of velocity are any unit of speed and any means of indicating a direction.
The velocity of light coming from a cars lights will be the speed of light C in the substance in front of the lights. It wont be the speed of light+the speed of the car however.
When you want to describe a speed or a velocity.
No, velocity is a vector, not a scalar. Metres per second is a way to express speed but to express velocity you also need a direction.
Light travels at the speed of light. There is no general velocity of light because velocity is a vector quantity, it also contains a direction and there is no preferred direction for light rays in general. Another answer: The speed of light has been calculated to be 186,000 miles per second.
The speed of anything is measured in metres per second. The difference between speed and velocity is that velocity is a vector, that is it has direction and well as magnitude. So velocity would be measured in metres per second in a certain direction.
