mass
Which of the following choices causes the atmosphere to be held in place around Earth?
Speed
Gravity
Work
Balance
In an investigation, Ross drops a basketball from a ladder and watches it fall to the ground. What is the force that pulls the basketball to the ground?
Acceleration
Distance
Gravity
Mass
London is conducting an experiment to see how far a marble will roll when she releases it at the top of an inclined plane. Why does the marble speed up as it travels down the inclined plane?
The marble has a greater mass as it travels faster.
The marble has less magnetic attraction to the inclined plane as it travels.
The force of gravity pulls the marble down the inclined plane.
The force of friction is reduced because the marbles surface is smooth.
Which sentences is not a true description of the effect of Earth’s gravity on objects?
Only objects that touch Earth are affected by Earth’s gravity.
Only objects with mass are affected by Earth’s gravity.
The farther away objects are from earth, the less affected they are by Earth’s gravity.
The closer objects are to Earth, the more affected they are by Earth’s gravity.
Why does the Moon orbit Earth?
There is a chemical attraction between the Earth and the Moon.
There is a gravitation attraction between the Earth and the Moon.
There is a magnetic attraction between the Earth and the Moon.
There is mechanical attraction between the Earth and the Moon.
Which of the following objects has the greatest gravity?
The moon
the sun
you
earth
A newton is fundamentally a measure of _____.
Force
momentum
energy
gravity
Which of the following is a correct explanation for astronaut “weightlessness”?
Astronauts continue to feel the pull of gravity in space, but they are so far from planets that the force is small.
Astronauts continue to feel the pull of gravity in space, but spacecraft have such powerful engines that those forces dominate, reducing effective weight
Astronauts do not feel the pull of gravity in space, because space is a vacuum.
Astronauts do not feel the pull of gravity in space, because black hole forces dominate the force field, reducing their masses
All of the following are considered Newton’s Laws except for:
An object in motion will continue in motion unless acted upon by an unbalanced force
For every action force, there is an equal and opposite reaction force.
Nature abhors a vacuum
Mass can be considered the ratio of force to acceleration.
A ball rolls down a smooth hill. You may ignore air resistance. Which of the following is a true statement?
The ball has more energy as the start of its descent than just before it hits the bottom of the hill, because it is higher up at the beginning.
The ball has less energy at the start of its descent than just before it hits the bottom of the hill, because it is moving more quickly at the end
The ball has the same energy throughout its descent, because positional energy is converted to energy of motion
The ball has the same energy throughout its descent, because a single object cannot gain or lose energy
A rocket launches from Earth’s surface and heads towards the moon. Which statement is true about the force of Earth’s gravity on the rocket during its trip?
The force of Earth’s gravity will increase as the rocket gets closer to the moon.
The force of Earth’s gravity will decrease as the rocket gets closer to the moon.
The force of Earth’s gravity will increase until the rocket leaves the atmosphere, at which point it will decrease as the rocket gets closer to the moon.
The force of Earths gravity will decrease until the rocket leaves the atmosphere, at which point it will increase as the rocket gets closer to the moon.
When is a hypothesis formed?
Before the data is taken
After the data is taken
After the data is analyzed
