Kepler's second law (law of equal areas) concludes that planets move faster when they are closer to the sun and slower when they are farther away, meaning they do not move at a constant speed as they orbit. This law helps explain the variation in orbital velocities of planets in their elliptical paths around the sun.
What else can I help you with?
Do planets revolve around the sun at the same speed?
No, planets do not revolve around the sun at the same speed. Their orbital speeds depend on their distance from the sun - planets closer to the sun have shorter orbital periods and faster speeds, while those further away have longer orbital periods and slower speeds.
Is constant speed constant velocity?
No. Velocity includes a direction vector, which speed does not have.
What is the speed of light on Mars?
Sound always travels at the same speed. The speed of sound varies by medium and temperature. Aerospaceweb seems to conclude that the speed of sound on the surface of Mars is roughly 550 mph.
What causes objects in the solar system to move predictably?
The laws of physics determine the movements of the planets and other bodies in the solar system. The moving planets tend to move in a straight line but the gravity of the sun pulls them inwards resulting in circular orbital movements around the sun. Since their is no significant friction or other forces t make the planets slow down, their speed is constant and solar gravity is constant, we can predict the motion of the planets with the right mathematical calculations.
Why acceleration produces at constant speed?
Acceleration by definition is a change in speed, direction, or both. If the speed is constant, the direction could still be changing. You can feel a change in direction, therefore you can feel acceleration even if the speed is constant.
What can you then conclude about the orbital speed of a planet in an elliptical orbit?
Kepler's Second Law: The planet moves faster when it is closer to the Sun.
If the plotted points on a speed time graph do not form a straight line what do you know about the objects acceleration?
You can conclude that the acceleration of the object is not constant.
Why does moons orbit the planets?
because the planets' gravity pull them so that they do not go away and the moons revolve around them with a constant speed so they stay in their orbit
What is speed that is unchanging called?
Constant speed
What is the different between constant velocity and constant speed?
constant velocity is when you maintain speed and direction, this usually is in a straight line, and constant speed means that your speed is always constant at all times.
Do planets revolve around the sun at the same speed?
No, planets do not revolve around the sun at the same speed. Their orbital speeds depend on their distance from the sun - planets closer to the sun have shorter orbital periods and faster speeds, while those further away have longer orbital periods and slower speeds.
How do you know when energy transforms?
By observation, and deduction. If, for example, an object's speed increases, you can conclude that its kinetic energy increases. The energy, of course, must come from somewhere, so there is some sort of energy transformation. If a car maintains a constant speed despite friction, you can conclude that the energy lost to friction must be compensated - in this case, by the engine. Etc.
Can an object have constant velocity and but variable speed?
No, an object cannot have constant velocity and variable speed. Velocity is a vector quantity that includes both speed and direction. If the object's velocity is constant, then its speed must also be constant.
Can you use average speed to calculate the speed of an object that is moving at a constant speed?
Yes, average speed can be used to calculate the speed of an object moving at a constant speed. This is because the average speed over a whole journey for an object moving at a constant speed is the same as its actual speed.
Speed that does not change is referred to as speed?
constant.. done by makayla smith..
What is non constant speed?
non-constant speed is when the speed for an object does not stay the same
If the speed of an object does not changed then the object is traveling at a?
If speed does not change then the object is moving with constant speed. when object moves in a circle its speed does not remains constant. Speed of object remains constant only if it moves along linear path.
