Gravitation

What is mass in the context of a science experiment?

• The amount of matter in an object

• The force that gravity exerts on an object

• The speed at which an object falls

• The distance between two objects

What is weight in the context of a physics class?

• The amount of matter in an object

• The force that gravity exerts on an object

• The speed at which an object falls

• The distance between two objects

What is the formula for calculating the force required to lift an object?

• F = m / g

• F = m + g

• F = m x g

• F = m - g

What is gravity in the context of space exploration?

• A force that changes an object's color

• A force that pulls objects toward each other

• A force that pushes objects apart

• A force that stops objects from moving

Why do objects fall at the same rate in a vacuum?

• Due to differences in shape

• Due to gravity

• Due to air resistance

• Due to differences in mass

What is gravitational field strength in the context of a roller coaster?

• The force that changes an object's color

• The force that pushes objects apart

• The force per unit mass experienced by an object in a gravitational field

• The force that pulls objects toward each other

Why do astronauts feel weightless in space?

• Due to the lack of oxygen

• Due to the lack of gravity

• Due to differences in mass

• Due to air resistance

Would a person weigh the same on different moons?

• Weight is determined by the color of the moon

• Weight is determined by the distance from the Earth

• No, weight depends on the gravitational field strength of the moon

• Yes, weight remains constant on all moons

What is the key takeaway from the lesson on gravitation?

• The speed of light in a vacuum

• The role of air resistance in falling objects

• The differences between mass and weight

• The color of different planets

What is the effect of gravity on Earth?

• To increase the speed of falling objects

• To change the color of objects

• To keep objects grounded and give them weight

• To push objects away from each other
