What were the two main classifications of motion in Aristotle's view of nature?
Aristotle classified motion into natural motion and violent motion. Natural motion was intrinsic to an object's nature, such as an apple falling from a tree. Violent motion was caused by an external force acting on an object, like pushing a ball.
What is the equations of motion for an object falling freely without any resistsnce?
You can any of several formulae for constant acceleration, found in any physics textbook. Acceleration due to gravity, near the Earth's surface, is about 9.8 meters/second2.
How is rotation different from revolution?
"Rotation" refers to an object's spinning motion about its own axis. "Revolution" refers the object's orbital motion around another object
What opposing forces act on an object falling freely through the atmosphere?
The forces that affect the rate of a falling object are Gravity and Air Resistance. Gravity affects the speed and the velocity of the object by speeding it up as it falls closer to the earth, and Air resistance works against the object pushing against it.
What is the law of freely falling bodies that Galileo created?
A freely falling object is an object that moves under the influence of gravity only. Neglecting air resistance, all objects in free fall in the earth's gravitational field have a constant acceleration that is directed towards the earth's center, or perpendicular to the earth's surface, and of magnitude g = 9.8 m/s 2. If motion is straight up and down and we choose a coordinate system with the positive y-axis pointing up and perpendicular to the earth's surface, we describe the motion with Eq.(2.7), Eq.(2.8), Eq.(2.9) with a - g , xy .Equations of Motion for the 1-d vertical motion of an object in free fall: * v = v0 - gt * y = v0t - gt 2 * v 2 = v02 - 2gy
Does an object that is freely falling have mass?
Yes, an object freely falling still has mass. Mass is a measure of the amount of matter in an object, and it remains constant regardless of the object's motion. The force of gravity acting on the object is what causes it to fall.
What is constant for freely falling body?
The acceleration due to gravity is constant for a freely falling body. This means that the object will experience a constant acceleration of 9.81 m/s^2 (on Earth) in the downward direction, regardless of its mass. This allows us to predict the motion of the object using equations of motion.
How equation of motion are modified for freely falling objects?
For freely falling objects, the equation of motion is modified to account only for the effects of gravity. The equation becomes: y = 0.5gt^2, where y is the height of the object at time "t" in seconds, and "g" is the acceleration due to gravity (approximately 9.8 m/s^2). Friction and other forces are typically ignored in these scenarios.
What is the only force acting on a freely falling object?
Gravity is forcing an object to fall to the ground. Another force is friction from air pressure on the falling object.
What is terminal motion?
Terminal motion typically refers to the final stage of an object's movement when it reaches a constant velocity or stops moving altogether due to the forces acting upon it. This can occur when an object reaches its maximum speed or when opposing forces come into equilibrium.
What Is the motion of a falling object when the only force acting on it is gravity.?
downward motion
Does the velocity of an object increase when its falling freely in a vacuum?
It accelerates at a higher rate
What force opposes the downward motion of falling object?
The force that opposes the downward motion of a falling object is air resistance, also known as drag force. This force acts in the opposite direction to the motion of the object and increases with the speed of the object.
What is the acceleration of a falling object that has reached it's terminal velocity?
At terminal velocity, the acceleration of a falling object is zero. Terminal velocity is the constant speed that a freely falling object eventually reaches when the resistance of the medium (such as air) through which it is falling equals the force of gravity.
What is the formula for calculating the velocity of an object falling freely under gravity, expressed as v2/2g?
The formula for calculating the velocity of an object falling freely under gravity is v2/2g, where v represents the velocity of the object and g represents the acceleration due to gravity.
What is constant for an object falling freely towards the earth?
The constant for an object falling freely towards the Earth is the acceleration due to gravity, which is approximately 9.8 m/s^2. This acceleration remains the same regardless of the mass of the object, resulting in all objects falling at the same rate in a vacuum.
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.
