Planets stay in orbit because of the gravitational pull of the Sun. Hope this helps
If there are two forces acting on a rocket, and the forces are equal and opposite, then they add up to zero, and there is no NET force at all on the rocket.
Then the rocket can only move at a constant speed in a straight line. It can't have any acceleration (change of speed or direction.)
Answer:
a loud explosive noise caused by the shock wave from an aircraft traveling faster than the speed of sound.
Explanation:
Answer:
29865.31 m/s
Explanation:
Radius of the Earth orbit if it is assumed to be circular = 1.5×10¹¹ m = r
<em>Circumference of the orbit = 2πr</em>
<em>= 2π×1.5×10¹¹</em>
<em>= 3π×10¹¹ m</em>
Time taken by Earth to complete one rotation around the orbit = 365.25 days
<em>Converting to seconds we get</em>
<em>365.25×24×60×60</em>
<em>= 31557600 seconds</em>
Velocity of Earth
∴ The average speed of Earth in its orbit is 29865.31 m/s
Acceleration, in physics, is the rate of change of velocity of an object with respect to time. <span> Anytime an object's velocity is changing, the object is said to be </span><span>accelerating. It can be calculated as follows:
acceleration = 8.2 - 3.5 / 1.5 = 3.1 m/s</span>²
Hope this answers the question.
