Lesson Worksheet: Gravity Science • 4th Grade

In this worksheet, we will practice defining the force of gravity and describing its effects on objects.

Q1:

Objects with greater mass have a stronger pull. Which of the objects given has the strongest gravitational pull?

• AA soccer ball
• BA bowling ball
• CA table tennis ball
• DA tennis ball

Q2:

Pick the correct word to fill in the blank: Earth’s gravity pulls objects .

• Aup
• Bdown
• Cleft
• Dright

Q3:

What force does the arrow show?

• AFriction
• BGravity
• CPush

Q4:

What is the name of the force that helps the child travel down a slide?

• AGravity
• BFriction

Q5:

Gravity is a noncontact force which pulls all objects toward each other.

Choose a word from the following to fill in the blank: The amount of gravity an object has depends on its .

• Amass
• Bvolume
• Cmomentum
• Dacceleration

Q6:

Objects with more mass have a stronger gravitational pull than objects with less mass.

Fill in the blank: The force of gravity is on the Moon than on Earth because the Moon has less mass than Earth.

• Asmaller
• Bbigger

Q7:

The force of gravity on the Moon is smaller than on Earth.

Fill in the blanks: An astronaut can jump higher on than on .

• AEarth, the Moon
• Bthe Moon, Earth

Fill in the blanks: This is because there is a force the astronaut to the ground.

• Aweaker, pushing
• Bweaker, pulling
• Cstronger, pushing
• Dstronger, pulling

Q8:

Weight is the force that gravity exerts on an object. What unit is weight measured in?

• ANewtons
• BKilograms
• CMeters

Q9:

This leaf is falling through the air. Air resistance pushes upward on the leaf.

Fill in the blank: The leaf falls because air resistance is not the only force acting on the leaf. The force of on the leaf.

• Agravity pushes up
• Bgravity pulls down

Q10:

This jar is resting on a table. The object has a weight force.

Fill in the blank: The jar does not fall through the table because the surface of the table the object with an equal force.

• Apushes up on
• Bpushes down on
