What else can I help you with?
How does the mass and weight change in different locations?
Mass always remains constant but weight changes due to the change in gravitational field strength. Gravitational field strength changes because: 1. The radius of the earth is not uniform. 2. The earth is rotating about its axis. 3. The density of the earth is not uniform.
Why does the sphere moving in a fluid become uniform after certain time?
The motion of a sphere in fluid becomes uniform over time due to the balance between gravitational forces and fluid resistance. As the sphere moves, the fluid creates a drag force that eventually equals the gravitational force acting on the sphere. This equilibrium causes the sphere to move at a constant velocity, resulting in a uniform motion.
What are two ways in which an object can have constant velocity uniform motion?
Objects moving in uniform circular motion will have a constant speed, and two objects with the same acceleration have a constant velocity.
Why is the accleration due to gravity same for all objects?
The acceleration due to gravity is the same for all objects because it is a constant value on Earth's surface. This value is approximately 9.81 m/s^2, regardless of the mass or size of the object. This uniform acceleration allows objects of different masses to fall at the same rate in a vacuum.
When an object falls freely to the ground its acceleration is uniform?
Yes, when an object falls freely due to gravity, its acceleration is uniform and equal to 9.8 m/s^2, directed towards the center of the Earth. This uniform acceleration is the result of the gravitational force acting on the object and is independent of the object's mass.
Does the Universal Law of Gravitation say that any two objects in the universe will exert a gravitational force on each other?
Yes, the Universal Law of Gravitation states that any two objects in the universe with mass will exert a gravitational force on each other. The strength of the force is directly proportional to the product of their masses and inversely proportional to the square of the distance between their centers.
Why uniform motion is not common?
Motion, uniform in both velocity and path (change of position), is uncommon, for each body is affected by the other bodies in the universe. The rotation of the Earth round the Sun is affected by the closeness of the other planets. Though the eccentricity of Earth's Solar orbit is very close to a perfect circle. And in mechanical objects such as motors, the effects of friction and gyroscopic effects are non-zero.
Objects at rest or in uniform motion have what acting on them?
zero net force
What is the term for motion in which the velocity of the moving objects does not change?
uniform motion
What does bowling uniform look like?
Every uniform is different.
What is the acceleration rate for falling objects?
If the objects are under free fall near the surface of the Earth, then they are under uniform acceleration due to gravity whose magnitude is 9.8ms-2 .In general, on the surface of a planet of mass m and radius r the acceleration due to gravity is Gm/r2, where G is Newton's gravitational constant.
What does a children school uniform look like?
Every school that requires a uniform has a different uniform.
How does the mass and weight change in different locations?
Mass always remains constant but weight changes due to the change in gravitational field strength. Gravitational field strength changes because: 1. The radius of the earth is not uniform. 2. The earth is rotating about its axis. 3. The density of the earth is not uniform.
When your in college Army ROTC do you get a uniform?
You get several different types of uniforms - PT uniform, dress uniform, ACU uniform, etc.
What happens to the period of mass of the objects increases in uniform circular motion?
