If the gravitational pull of the sun is the most then why doesn't it pull the planets towards it?
It does. The planets have velocity and inertia that keep them in orbit; but they really ARE continuously falling towards the Sun, their velocity makes them miss it constantly though!
How will the upward force of air resistance compare to the downwward pull of gravity?
Assuming that you're referring to an object that is accelerating towards a massive body by means of gravitational attraction... When the force of frictional air resistance equals the opposing force of gravity, the net force on the object equals zero, and acceleration will cease. It is called terminal velocity, and the object will remain at this velocity until some new event happens.
What is the relationship between air resistance and the acceleration of falling objects?
As an object falls towards the earth, it accelerates due to the force of gravity acting on it's mass. As velocity increases, air resistance increases. This is in the opposite direction to the force of gravity on the object. Therefore the resultant force on the object is decreased, and the rate of acceleration is reduced. Eventually, the force due to the air resistance is equal in magnitude to the weight and the object has no resultant force acting. At this point the object will be travelling at a constant velocity, commonly referred to as Terminal Velocity.
How is tangental velocity related to the moon falling around the earth?
Tangential velocity is the velocity at which an object moves along a curved path. In the case of the moon orbiting the Earth, the tangential velocity of the moon allows it to stay in its orbit and not fall into the Earth due to the balance between the gravitational force pulling it towards Earth and the centripetal force keeping it in orbit.
What causes a satellite to stay in orbit rather than falling towards earth?
Its forward motion. Please understand that something in orbit IS falling towards Earth.
Does a skydivers decreases her acceleration when falling 5 seconds before reaching her terminal velocity?
No, a skydiver's acceleration remains constant as they fall towards their terminal velocity. This is because terminal velocity is the point at which the forces of gravity and air resistance are balanced, resulting in a constant velocity.
Ignoring air resistance what is the velocity of an object falling toward the surface of the earth?
The velocity of an object falling towards the surface of the Earth will increase by a rate of approximately 9.8 m/s² due to gravity. This acceleration would continue until the object reaches terminal velocity or impacts the surface of the Earth.
What is terminal velocity and how to control it and why it occurs?
Terminal velocity is when air resistance balances out with gravity. For humans it's usually around 2000 ft of falling, gravity accelerates the person towards the ground at about 9.8m/s, as said person speeds up, air resistance increases and it becomes harder to accelerate. Terminal velocity is the point at which one may no longer accelerate. To control it: more air resistance = slower descent (terminal velocity comes sooner and is not as fast (i.e.parachutes), less air resistance = faster descent, it may take longer to reach terminal velocity as it is a much higher speed.
When will in object falling towards earth stop accelerating?
An object falling towards the Earth will stop accelerating once it reaches its terminal velocity, which is the maximum speed it can achieve due to air resistance. This happens when the force of air resistance is equal to the force of gravity acting on the object.
A skydiver steps from a helicopter and falls for 5 seconds before reaching her terminal velocity During this 5 second interval her acceleration will?
increase- your speed will increase until terminal velocity is reached. From there it will stay constant.
What is the force for dropping a pen?
The force acting on a falling pen is gravity, which pulls it downward towards the Earth. This force causes the pen to accelerate towards the ground until it reaches a terminal velocity when air resistance balances out the gravitational force.
Explain the term terminal velocity?
The point at which the acceleration due to gravity is equal to the friction of the air dragging on the object (generally). When the two are equal, they cancel out and no more acceleration occurs, causing the object to have attained the fastest speed possible.
What is change in the velocity of a falling object?
Any change in the velocity of anything is known as 'acceleration'. In the case of a falling object near the Earth's surface, the direction of the velocity is constant, and its magnitude increases by 9.8 meters (32.2 feet) per second, every second.
What does a parachute do to terminal velocity?
A parachute increases drag, slowing the fall of an object and reducing its terminal velocity. As the parachute deploys, it captures air and creates resistance, causing the object to fall more slowly towards the ground.
What is the velocity of the object falling toward the surface of the earth?
The velocity of an object falling towards the surface of the Earth will increase approximately by 9.8 m/s every second due to gravity, assuming air resistance is negligible. This velocity will continue to increase until the object reaches its terminal velocity or collides with the Earth.
Will the velocity of an object increase decrease or remain constant as it reaches the ground?
The velocity of an object will increase as it falls towards the ground due to the acceleration of gravity. However, once it reaches terminal velocity, its velocity will remain constant.
If the gravitational pull of the sun is the most then why doesn't it pull the planets towards it?
It does. The planets have velocity and inertia that keep them in orbit; but they really ARE continuously falling towards the Sun, their velocity makes them miss it constantly though!
