B. Rain falling from the sky
C. Water evaporating
D. Lightning
B. Rain falling from the sky
What happens to an object when earth's gravity pulls on it.
It can move toward earth
What is fromation that supports an idea
Evidence
In which direction does earth ='s gravitational force pull objects?
Towards the center of earth
Which has the weaker gravitational pull?
The moon
A student drops a pencil.What happens?
The pencil falls toward the ground because of gravity.
A ball is sitting on a table. Is gravity still acting on the ball?
Yes
What is a large celestial body that revolves around the Sun
Planet
Earth's gravitational force has it greatest effect on what?
Objects near earth's surface
Complete the sentence: Earth's gravity is ______ than the moon's gravity
Stronger
Which example best shows gravity moving an object?
A. Sliding a book across a table
B. Placing a book on a shelf
C. Dropping a book to the floor
D. Turning a book face down
C. Dropping a book to the floor
A student says gravity only affects objects when they are falling. Do you agree or disagree?
Gravity acts on objects even when they are not falling.
What force causes objects with mass to attract each other
Gravity
Two balls have the same mass. One ball is close to Earth's surface, and the other is much farther away. Which ball would experience a greater effect from Earth's gravity?
The ball closer to Earth's surface.
Why can we stay on earth's surface?
Earth gravity pulls us towards the ground
A student wants to prove that gravity is acting on a ball. Which observation would provide the strongest evidence?
A. The ball is red.
B. The ball has a certain mass.
C. The ball falls toward the ground when released.
D. The ball is round.
C. The ball falls toward the ground when released.
A ball is thrown upward. At first, the ball moves upward, but then it comes back down. What force causes the ball to return toward Earth?
Gravity
Which vocabulary word describes a push or pull, while another describes information that supports an idea?
Force and evidence
A student says, “Gravity makes objects fall, but gravity cannot change the motion of an object that is already moving.” Is the student correct? Explain.
No. Gravity is a force that can change an object's motion. For example, gravity can cause a moving ball to change its direction as it moves toward the ground.
Explain how earth's gravity affects the moon
Earth's Gravity helps keep the moon near earth.
A book is sitting on a table. A student says, “Gravity is not acting on the book because the book isn't moving.” Is the student correct? Explain.
No. Gravity is still acting on the book. Gravity is a force acting on objects, even when an object is not visibly moving.
A student drops a ball on Earth and another ball on the Moon. Both balls are affected by gravity. Predict which ball would experience a stronger gravitational pull and explain why.
The ball on Earth would experience a stronger gravitational pull because Earth's gravity is stronger than the Moon's gravity.
