If the gravitational force between the earth and object always causes the same acceleration why does a feather fall more slowly than a hammer does?
The feather falls more slowly than the hammer due to air resistance. The feather has a larger surface area-to-mass ratio, which causes more air resistance compared to the hammer, falling at a slower speed. Without air resistance, both objects would fall at the same rate due to experiencing the same gravitational force.
What else can I help you with?
Are gravitational forces always present in interactions between celestial bodies?
Yes, gravitational forces are always present in interactions between celestial bodies.
Why is the acceleration vector is always at 90 degrees to the velocity vector?
That's only true when the object is in circular motion.The circular motion is the result of a force (which produces acceleration)that's always perpendicular to the object's velocity.Like the gravitational force between the Earth and a geostationary satellite,or the tension in the string of a yo-yo that's doing circles.
What is a main difference between gravitational and electr onic forces is that electrical forces?
The main difference between gravitational and electronic forces is that electrical forces originate from the interaction between charged particles, such as electrons and protons, while gravitational forces arise from the mass of objects. Additionally, electrical forces can be attractive or repulsive based on the charges involved, whereas gravity is always an attractive force between masses.
Which change will always result in an increase in the gravitational force between two objects?
Reducing the distance between them. In theory, also increasing the mass; but you can't really change the mass of an object. However, you can compare the forces if you replace an object by a different object, which has a different mass.
What is the force produced by gravity acting on mass?
The force produced by gravity acting on a mass is known as weight. Weight is calculated as the mass of an object multiplied by the acceleration due to gravity. This force is proportional to the mass of the object and the strength of the gravitational field.
Can you calculate gravitational acceleration witn only having the time and the mass of the object?
Gravitational acceleration is always g = 9.8
Are gravitational forces always present in interactions between celestial bodies?
Yes, gravitational forces are always present in interactions between celestial bodies.
When Is the gravitational pull between two objects that have greater masses?
The gravitational pull is always present: there is no "when".
What is the acceleration of a projectile at the peak of its trajectory?
Assuming negligible air resistance, the acceleration of a projectile near the Earth's surface is always the gravitational 9.81 m/sec/sec downwards, regardless of where in the trajectory the projectile is.
What is the direction of acceleration due to gravity State with reason?
The acceleration between two bodies is always towards the centre of mass of the bodies in question.
What is the rate of acceleration that gravity puts on all falling objects?
The rate of acceleration depends on two factors according to the equation a = GM/d2, where G is the gravitational constant, M is the mass of the planet/larger object and d is the distance between the two masses. For example the acceleration on Earth's surface is "always" 9.8ms-2 because neither the mass of the Earth and the distance from its centre ever change*.
Why is the acceleration vector is always at 90 degrees to the velocity vector?
That's only true when the object is in circular motion.The circular motion is the result of a force (which produces acceleration)that's always perpendicular to the object's velocity.Like the gravitational force between the Earth and a geostationary satellite,or the tension in the string of a yo-yo that's doing circles.
Is angular momentum always parallel to angular acceleration?
momentum is product of moment of inertia and angular velocity. There is always a 90 degree phase difference between velocity and acceleration vector in circular motion therefore angular momentum and acceleration can never be parallel
What is the gravitational force acting upon an astronaut when lifting off?
The actual gravitational force on the astronaut ... the force attracting him to themass of the earth ... is exactly the same as it always is, and is equal to his weight.But ... he feels as if there's more force on him, as if his weight has increased.That's because he's accelerating aboard the launch vehicle, and there's no wayto tell the difference between the force of gravity and the force of acceleration.
What is the acceleration of a planet around the sun?
A planet is always accelerating towards the sun (exactly) because that is where the force of attraction comes from. But the planets are also moving quickly in their orbits, so instead of plunging into the sun they stay in nearly-circular orbits instead, in which they continuously curve towards the sun.
What is the relationship between velocity and gravity?
The relationship between force and acceleration mathematically is proportional, as seen in the second low of motion F = m*a. The acceleration of an object will be equal to the ratio of the net force on the object to the mass.
What is a main difference between gravitational and electr onic forces is that electrical forces?
The main difference between gravitational and electronic forces is that electrical forces originate from the interaction between charged particles, such as electrons and protons, while gravitational forces arise from the mass of objects.
