Why does an orbiting satellites speed remain constant?
The satellite will not change speedbecause the gravity of the earth is a perpendicular force which only affectsdirection and not speed. Parallel forces must beapplied in order to change speed, butperpendicular forces only change direction.
How does the mass of a planet affect the speed of a moon that orbits it?
The mass of a planet affects the speed of a moon that orbits it through gravity. The greater the mass of a planet, the stronger the gravitational force it exerts on its moon, causing the moon to orbit at a faster speed to counteract this force. Therefore, a more massive planet typically results in a faster orbiting speed for its moon.
Why an object in a circular orbit at constant speed is experiencing an accelaratiopn?
An object in circular orbit at constant speed is experiencing an acceleration because the orbit is circular. That is, an object is accelerating not just when its speed is changing but also when its direction is changing. In physics, acceleration refers to a change in velocity which is composed of speed and direction. Hence both a change in speed and a change in direction are, by definition, a form of acceleration.
The moon revolves aroung earth at a fairly constant speed is the moon accelarating?
The Moon's speed is very constant. There are 2 kinds of acceleration: Linear and Centripital. Centripital acceleration is experienced by a body orbiting another body, like the Moon orbits the Earth, but it does not mean speeding up.
Why does the speed of a satellite undergo change in an elliptical orbit?
The speed of a satellite changes in an elliptical orbit because the satellite moves faster when it is closer to the central body due to gravitational acceleration, and slower when it is farther away. This change in speed is necessary to balance the varying gravitational force experienced by the satellite at different points in its orbit.
How is Acceleration related to speed?
Acceleration is the rate of change of velocity (not speed). Acceleration is the rate of change of velocity over time. Velocity is defined by speed and direction. A satellite orbiting the earth at a constant speed is still accelerating because gravity is making it travel in a circle (or ellipse) and consequently its direction and therefore its velocity is constantly changing.
How is acceleration related to the change in speed?
A change in speed (and/or direction) is acceleration.
How does a change in speed affect acceleration?
Acceleration is directly proportional to the change in speed. If the speed increases, acceleration is positive. If the speed decreases, acceleration is negative. The magnitude of acceleration is determined by the rate at which the speed changes.
How do you calculate time with speed and acceleration?
Average acceleration = Change in speed/time so Time = Change in speed/Average acceleration
The relationship of speed and acceleration?
Acceleration is the time rate of change of speed. Acceleration = speed/time.
Which Planet of solar system with fastest orbiting speed?
Mercury
For a car moving around a circular track at a constant speed the acceleration is?
constant speed=0 acceleration Acceleration is the change in speed. If the speed doesn't change(ie constant) the acceleration is zero.
What is the different between motion and acceleration?
Motion is about speed of location change, acceleration is about speed change.
How is increasing speed acceleration?
By definition acceleration is the change in velocity (speed).
How do you find the acceleration?
Acceleration = (change in speed) divided by (time for the change)
Why does acceleration change when speed does not?
Acceleration is the rate of change of speed, so if speed is constant, acceleration is zero. However, if speed is constant but direction is changing (e.g. moving in a circle at constant speed), the velocity is changing, and thus there is still acceleration.
Can acceleration change with out increase or decrease speed?
yes the 3 types of acceleration are increased speed decrease speed or change in direction.
