What is the effect of gravity on objects on the surface of Earth Check all that apply?
A- Gravity pulls objects toward Earth at a rate of 9.8 m/s2. Weight is the result of gravity’s pull on a mass on Earth’s surface. Why are objects that fall near Earth’s surface rarely in free fall? Gravity does not act on objects near Earth’s surface.
What is an effect of gravity on objects?
The size of the gravitational force is proportional to the masses of the objects and weakens as the distance between them increases. Both objects exert an equal attractive force on each other: a falling object is attracting the Earth with the same size force as the Earth is attracting it.
Which best describes the gravitational force between the twin satellites?
Which best describes the gravitational force between the twin satellites? It increased by 1/2.
What event will produce the greatest increase in the gravitational force between the two masses?
The scale reading will decrease momentarily then will increase as the student is moving upward from the scale. What event will produce the greatest increase in the gravitational force between the two masses? large downward force although the universal gravitational constant is very small.
Why are satellites placed into orbit at least?
Why are satellites placed into orbit at least 150 km above Earth’s surface? to avoid air resistance. to match Earth’s curvature. to create inertia. to increase friction.
Which best describes Sid’s error?
Which best describes Sid’s error? Tangential speed changes throughout a satellite’s orbit.
Which best describes Sid’s error Brainly?
Tangential speed changes throughout a satellite’s orbit. Centripetal force can sometimes slow down a satellite in orbit. …
How can Brendan correct his diagram?
Brendan drew a diagram to illustrate the centripetal force acting on a satellite. How can Brendan correct his diagram? Change the Fg = Fc vector so it is perpendicular to the v vector. Enrique is given information about a satellite orbiting Earth.
What would cause the greatest increase in acceleration of a satellite?
Answer: A decrease in the radius and an increase in the tangential speed.
What causes a satellite to move tangentially?
The speed of the satellite and the force of the gravity on the satellite then the result , the satellite moves around the earth in a circular motion. A satellite to move tangentially to a circular path, while revolving around the circular path because the centripetal force is acting on it.
Which best explains why astronauts appear weightless?
Which best explains why astronauts appear weightless when they are in a space shuttle orbiting Earth? They are falling toward Earth at the same rate as the space shuttle.
Which object would be considered to be in free fall one that experiences?
one that experiences both friction and centripetal force. one that is truly weightless. one that is slowed down by air resistance.
Why do heavy and light objects fall at the same rate?
Because the downward force on an object is equal to its mass multiplied by g, heavier objects have a greater downward force. Heavier objects, however, also have more inertia, which means they resist moving more than lighter objects do, and so heaver objects need more force to get them going at the same rate.
What forces act on a body falling freely through air?
gravity
