What is the kind of motion that causes objects to move in a circle?
The kind of motion that causes objects to move in a circle is formed or produced when the object is suspended from another object that is stationary. And because the moving object is suspended it will be subject to gravity which will cause it to move in a circle or circular-like motion. The actual kind or cause of the motion is a simple swaying or arc-like motion.
Explain Archimedes principle and how he came to formulate it?
Archimedes Principle simply states that the buoyant force acting on an object equals the weight (force of gravity) of the fluid displaced by the object. He came to formulate it when he was in the tub, he noticed that before he got in, the water was at the rim and after he got in, the water had spilled over the top.
What does apply negtive force to absorb a objects knetc energy mean?
There is really no such thing as "negative force" (force is a vector quantity); in this case, it must be an informal way to refer to a force acting in the direction opposite to the object's movement.
How does gravity affect speed?
It is gravity that creates the force that causes an object to fall. We know that gravity is a function of mass, and the mass of the objects being considered will have an effect on how fast they fall. Additionally, the shape of the object will have something to do with how fast it falls. A flat piece of cardboard will not fall as fast as a glass ball of the same mass.
Why does an object in deep outer space carry on moving at the same steady speed even if there are no forces acting on it?
Because there's nothing to stop it. Newton's 1st law of motion states that an object at rest will stay at rest, and a moving object will continue to move at the same velocity, unless a force acts upon it. A moving car stops when it loses power because of friction between the tires and the road acting upon it, a thrown ball loses forward velocity and gains downward velocity because of gravity acting up on it; nothing stops moving, or moves slower, unless an outside force causes it to do so.
What forces act on falling objects?
The main forces acting on a falling object are gravity, which pulls the object downwards towards the center of the Earth, and air resistance, which opposes the motion of the object as it falls through the air.
Why do falling objects accelerate at first?
Falling objects accelerate due to the force of gravity acting upon them. As the object falls, the force of gravity pulls it downward, increasing its speed. This acceleration continues until the object reaches terminal velocity or encounters another force counteracting gravity.
How is gravity different for objects that freely fall down and those thrown upwards?
The gravity acting on a rising object and that on a falling object are the same when these objects are at the same height. What is different is that a rising object is decelerating by the force of gravity and the falling object is accelerating.
When the only force acting on a falling object is the object is in free fall?
Gravity.
What is the force that supports an object against gravity?
The force that supports an object against gravity is called the normal force. It is exerted by a surface to prevent objects from falling through it. The normal force equals the force of gravity acting on the object.
What are the impacts of relativistic gravity on falling objects on light?
what are the impacts of relativistic gravity on falling object on ligh?
What causes falling objects to speed up as they fall?
Falling objects speed up due to the acceleration of gravity acting on them. As an object falls, the force of gravity pulls it downward, causing it to accelerate. This acceleration causes the object to increase in speed until it reaches terminal velocity or hits the ground.
What is the amount of gravity acting an objects mass?
The amount of gravity acting on an object is determined by its mass. The greater the mass of the object, the stronger the force of gravity acting on it. Gravity is a force that pulls objects towards each other, with the strength of the force depending on the masses of the objects and the distance between them.
Is there any force acting on an object which is falling freely?
Yes. The definition of "free fall" implies that gravity from Earth - or perhaps from different objects - is acting on the body.
When the only force acting on an falling object is gravity the object is said to be?
In free fall.
What is the speed limit of falling objects called?
The speed limit of falling objects is called terminal velocity. This is the constant speed that a freely falling object eventually reaches when the resistance of the medium it is falling through (like air) equals the force of gravity acting on it.
What are the forces acting on a falling object on earth?
Gravity and air resistance.
