What unit measures vibration?
Vibration has amplitude and frequency, usually defined by acceleration and cycles per second (Hertz). It is measured with an accelerometer.
Which of the units that can be used to describe vector quantities?
Units that are used for measures in which the direction is relevant. Example are displacement, velocity, acceleration, force.
How can you use a graph to show acceleration?
With great difficulty. Acceleration is a vector and that means that it has a direction as well as a magnitude (size). For motion in a plane, the only effective way to show acceleration is to draw lots of arrows from points at regular intervals in a plane such that the length of the arrow is a measure of the magnitude of the acceleration and the direction of the arrow coincides with that of the acceleration. An answer referring to a speed-time graph is totally incorrect. That measures speed in the radial direction only. All apects of motion (displacement, speed, acceleration) in a transsverse direction are completely ignored.
What is the application for vector calculus?
Measures of motion (displacement, velocity, acceleration) and forces are all vectors so any study involving these would require vector calculus.
What is the difference between gravitational acceleration and acceleration?
Gravitational acceleration is simply acceleration due to gravity.
What does acceleration measure?
Acceleration measures the change in speed
Measures the changes in velocity?
Acceleration measures the changes in velocity over time. It can be positive (speeding up), negative (slowing down), or zero (constant velocity).
What measures acceleration on a speed-time graph?
The slope.
When traveling at a constant velocity the acceleration is?
When traveling at a constant velocity, the acceleration is zero. This is because acceleration measures the rate of change of velocity, and if velocity is not changing, there is no acceleration.
How is a speed graph different from an acceleration graph?
A speed graph measures the distance devided over time. Acceleration graph measures the change in speed over time.
On speed-time graph the measures acceleration?
On speed-time graph can measure acceleration by getting the slope.
What is the rate of change and of speed and direction?
acceleration
What do acceleration data loggers measure?
An acceleration data logger measures and records the activity and motion. They are used to find the activity of temperature, humidity, and pressure.
What is the measure of a body's resistance to acceleration?
The measure of a body's resistance to acceleration is its inertia, which is proportional to its mass. The greater the mass of an object, the more force is needed to accelerate it.
What is the quantitative to describe motion?
Speed, velocity, and acceleration are common quantitative measures used to describe motion. Speed is the distance traveled per unit of time, velocity specifies both speed and direction, and acceleration measures the rate of change of velocity.
Can a body be in motion but 0 acceleration?
Yes, a body can be in motion but have zero acceleration if it is moving at a constant speed in a straight line. Acceleration measures the rate of change of velocity, so if velocity is constant, acceleration is zero even though the body is in motion.
How is acceleration similar to speed and velocity?
Acceleration, speed, and velocity are all related to an object's motion. Acceleration measures the change in velocity over time, while speed simply measures how fast an object is moving without regard to direction. Velocity, on the other hand, includes information about both the speed and direction of motion.
