When either a linear or angular speed is changing with time the difference in speed per unit time is called the?

â 13y ago
The rate at which speed changes with respect to time is called acceleration. It can refer to changes in linear speed (velocity) or angular speed. Positive acceleration indicates an increase in speed, while negative acceleration (deceleration) indicates a decrease in speed.

Can uniform angular velocity has acceleration?
No, uniform angular velocity implies that an object is moving in a circle at a constant rate. Since acceleration is defined as any change in velocity (either speed or direction), if the angular velocity is constant, there is no acceleration present.
Relation between linear speed and angular velocity?
Linear speed is directly proportional to the radius of rotation and the angular velocity. The equation that relates linear speed (v), angular velocity (Ī), and radius (r) is v = rĪ. This means that the linear speed increases as either the angular velocity or the radius of rotation increases.
What is meant by uniform and non uniform motion?
Uniform motion is when an object covers equal distances in equal intervals of time, moving at a constant speed in a straight line. Non-uniform motion is when an object covers unequal distances in equal intervals of time, either changing its speed, direction, or both.
Explain the term angular velocity?
Angular velocity is a measure of how fast an object is rotating around a specific point or axis. It is typically measured in radians per second and describes the rate of change of angular displacement. A higher angular velocity indicates a faster rotation of the object.
Is how fast velocity is changing at a specific instant?
The rate at which velocity is changing at a specific instant is called acceleration. It measures how quickly an object's velocity is changing, either by speeding up (positive acceleration) or slowing down (negative acceleration). It is the second derivative of an object's position with respect to time.
What is the angular measurement of 0-90 degrees taken from a north or a south line and oriented toward either east or west called?

What do Parallel measure?
Latitude,the angular distance from the equator toward either pole.
How do you take difference of latitude?
Latitude is your distance or angular measurement from the equator. Either north or south. Without using a GPS system the best way is to measure the angle of the sun above the horizon at local noon.

What is the difference between angular unconformity disconformity and nonconformity?
Angular unconformity is when rocks are deformed and then eroded and then new sediment is deposited on top. Disconformity is when igneous or metamorphic rocks are eroded and then sediment is deposited on top. Nonconformity is when either there is no deposition for some time and then deposition resumes or horizontal layers are eroded (but not deformed in any way) and then deposition resumes. These create gaps in the rock record.
What is meant by uniform and non uniform motion?
Uniform motion is when an object covers equal distances in equal intervals of time, moving at a constant speed in a straight line. Non-uniform motion is when an object covers unequal distances in equal intervals of time, either changing its speed, direction, or both.
The process of changing velocity?
Changing velocity involves either increasing or decreasing speed, or changing direction. This can be achieved through acceleration, which is the rate of change of velocity over time. In other words, when an object speeds up, slows down, or changes its direction, its velocity is changing.
Jet engine works on either on conservation of linear momentum or angular momentum?
it works on the basis of conservation of linear momentum
What is the value of sin22?
That depends on what angular measurement is used. Set your scientific calculator to the desired angular measurement (either degrees, or radians), then press 22, followed by sin. Or in more modern calculators, you press sin, followed by 22, instead.

If your speed is changing but your direction is constant are you accelerating?
We all grew up thinking that 'acceleration' means picking up speed, because the gas pedal in the car is called the 'accelerator'. We have to get over it if we want to understand some elementary Physics. 'Acceleration' means either speed or direction (or both) is changing. If one or the other is changing, then there is 'acceleration', even if the other is constant. And if it's the speed that's changing, then it can be speeding up or slowing down ... it's 'acceleration' either way.
