Science 6 Q3 Lesson 3 Gravitational Forces - pt. 2

What is weight?

• The volume of an object

• The speed of an object

• The force exerted by gravity on an object

• The mass of an object

What happens to the gravitational force between two objects as they are separated?

• It becomes repulsive

• It decreases

• It remains the same

• It increases

What is the effect of distance on gravitational force?

• The farther the objects, the greater the force

• The closer the objects, the greater the force

• The effect is random

• Distance has no effect on gravitational force

What happens to the speed of falling objects on Earth and the moon?

• Objects fall faster on Earth

• Speed remains the same on both Earth and the moon

• Objects fall faster on the moon

• Objects do not fall on the moon

What is the Zero-G facility used for by NASA?

• To simulate gravity on Mars

• To study air resistance

• To test aircraft engines

• To conduct experiments in zero gravity

What is the relationship between mass and gravitational force?

• The greater the mass, the greater the gravitational force

• Mass has no effect on gravitational force

• Mass and gravitational force are unrelated

• The smaller the mass, the greater the gravitational force

What is the effect of air resistance on falling objects?

• It speeds up the fall

• It slows down the fall

• It changes the direction of fall

• It has no effect

What happens to the weight of objects on the moon compared to Earth?

• Objects float on the moon

• Objects weigh less on the moon

• Objects weigh more on the moon

• Weight remains the same

What is the relationship between separation distance and gravitational force?

• The force remains constant

• The force decreases with distance

• The force becomes repulsive

• The force increases linearly with distance

What is the acceleration due to gravity?

• The rate at which objects fall

• The distance between two objects

• The force of gravity on an object

• The speed of falling objects
