What is the equation for angular size?
We can generate another simple formula: Angular size in degrees = (size * 57.29) / distance No doubt you can figure out the formulas for minutes and seconds of arc.
What is the diameter of the moon?
3,474.2 km
What is the angular diameter of the moon?
about 31 arcmin
What is Sun’s diameter?
1.3927 million km
Is angular diameter an angle?
Angular diameter is, in fact, an angle, not a diameter. It is the angle that an object “takes up” as seen by an observer at a specified distance. This can be measured in degrees (°) or radians (rad). One circle takes up 360° and 2π rad, so 1 rad = 360/2π = 57.3°.
How does size affect distance?
Whatever be the size of two objects; if they have the same speed, they will cover the same distance in a given time. But, usually objects with a better aerodynamic design will move faster (i.e. have a greater speed) than a similar object with a poor aerodynamic design.
Do heavier objects travel further?
The heavy object will feel small changes to its speed (its acceleration is close to zero), while the light object will slow down a lot (its acceleration is a large negative number). In the end, the heavy object will travel farther, since it was less affected by air resistance.
How does the mass of a ball affect the distance the ball travels?
Whether on the ground or in the air, a variety of forces contribute to the motion of a ball. When two balls of the same diameter are made of materials of different density and mass, the ball with the greater mass-density will travel farther if projected with the same amount of force, or at the same initial speed.
Does the mass of a ball affect how far it travels?
Because of this, the mass cancels out and should not affect the rolling speed. In fact, it should be the radius of the ball that affects the rolling speed. Naturally, heavier balls are bigger and they thus roll faster because of their size, not their mass.
How does weight affect the distance an object travels?
The weight of an object influences the distance it can travel. Objects with a higher mass-density therefore travel faster and farther than those with a low mass-density, but only if they are launched with an infinite amount of force. …
