What Factors Affect Gravity?

Calculate what the weight of a bowling ball would be on Venus and Earth. Multiply the bowling ball's mass by the acceleration due to gravity on each planet, and write the solution in the last column of the table. Bowling Ball Mass = 7 kg. Acceleration Due to Gravity on Venus = 8.9 m/s². Acceleration Due to Gravity on Earth = 9.8 m/s².

• Bowling Ball Weight on Venus = 62.3 N. Bowling Ball Weight on Earth = 68.6 N.

• Bowling Ball Weight on Venus = 70.3 N. Bowling Ball Weight on Earth = 75.6 N.

• Bowling Ball Weight on Venus = 56.3 N. Bowling Ball Weight on Earth = 60.6 N.

• Bowling Ball Weight on Venus = 50.3 N. Bowling Ball Weight on Earth = 55.6 N.

As the masses of the different planets increase, what happens to the bowling ball’s weight?

• The bowling ball’s weight increases.

• The bowling ball’s weight decreases.

• The bowling ball’s weight stays the same.

• The bowling ball’s weight disappears.

On which of the planets in the table above does the bowling ball experience the greatest force of gravity?

• Earth

• Mars

• Venus

• Jupiter

What is the relationship between the mass of each planet and the force of gravity?

• The force of gravity increases as the mass of the planet increases.

• The force of gravity decreases as the mass of the planet increases.

• The force of gravity remains the same regardless of the planet's mass.

• The force of gravity is not affected by the mass of the planet.

Circle the name of the planetary object that exerts a greater force of gravity on Earth.

• Moon

• Jupiter

The relationship between the mass of each planetary object and the force of gravity is different from the first table because:

• Distance is another variable affecting the force of gravity, not just mass.

• Jupiter always exerts more gravity than the Moon due to its mass.

• The Moon is closer to Earth, so it has more mass than Jupiter.

• Gravity is only affected by the mass of the objects, not distance.

As the distance from Earth increases, what happens to the force of gravity?

• The force of gravity decreases.

• The force of gravity increases.

• The force of gravity remains the same.

• The force of gravity fluctuates unpredictably.

Based on your observations from both tables, name two factors that affect the force of gravity.

• Mass and distance.

• Temperature and color.

• Volume and shape.

• Speed and direction.

Show what you know about Isaac Newton’s First Law of Motion! Match each vocabulary term to its definition by writing the correct letter on the line. 1. _______ Force

• c. when all the forces acting on an object create a net force of zero, and the object does not move

• d. the tendency of an object to continue its current motion or lack of motion

• a. resistance to motion that occurs when surfaces are in contact with each other

• b. an attractive force that all objects exert on each other

• h. any push or pull on an object
