On which object will Earth’s gravity act with the greatest magnitude? (1 point) (1) On which object will Earth’s gravity act with the greatest magnitude?
a piano
(2) Why does a beach ball weigh less than a bowling ball?
The beach ball is less strongly attracted to the Earth.
(3) Which statement about gravitational attraction is correct?
All objects with mass experience gravitational attraction.
(4) A spacecraft flies within 500,000 km of each of these planets. Based on its mass, which planet would attract the spacecraft the least gravitationally?
March
(5) A student conducts an investigation to study the effect of gravity on objects of different masses. Which step should be the first in the investigation?
Find objects of different masses and measure them.
(6) A science class conducts an investigation to see how gravity affects objects of different masses. They drop three balls from the same height. They calculate the time it takes for the balls to hit the ground. What are the students comparing?
the time it takes for each ball to fall
(7) A hammer and a feather fall from the same height. Imagine that there is no resistance to the movement of objects in the air. What value will be different for the two objects?
the downward pull of gravity
(8) A coin (5 grams), a small parachute (21 grams) and a hammer (710 grams) are all dropped from a height of 10 meters. The coin and the hammer take about the same time to fall. Which statement describes the time it takes for the parachute to drop?
It takes longer to fall because it experiences greater air resistance.
(9) Which object would have the slowest velocity at terminal velocity?
a 50 kilogram block with a large parachute
(10) How does an open parachute slow down a skydiver’s fall?
The parachute increases the force that opposes gravity.
(11) A science class prepares an investigation of gravity and objects on Earth. In three or four sentences, explain the steps the class needs to take to provide data that will help them come to a conclusion about the effect of gravity on objects of different masses.
(change answer to own words) Obtain objects with different masses, time falls.
(12) Two paratroopers of different masses jump from an airplane. In three to five sentences, explain how their falls compare, including the effects of gravity, mass, and air resistance.
(change the answer to your own words) The skydiver with more mass would be more strongly affected by gravity, but air resistance would negate this slightly.
🐈 In case anyone confuses number 7, that is, GRAVITATIONAL ATTRACTION BETWEEN EARTH AND OBJECTS IYS only use write-in responses for assessments that open in new tabs, they are changing the answers. if the assessment opens in the homework page, you can use the letter answers the one with the highest mass. The “crying” guys are right…at least on the multiple choice questions. thank you soooooooooooooophhhhh crying is 100% correct thank you! YAY
6,9 and 10 are wrong but the rest is right thanks Does anyone know the answer to number 7? Nvm the gravitational attraction between Earth and objects it’s number 7 Cry it’s true I agree with Wes I DID THE TEST SO HERE
