Unit (2) Gravitational and Magnetic Forces Quiz

What two factors determine the gravitational force between two objects?

• Mass and distance
• Speed and direction
• Temperature and pressure
• Size and shape

What happens to the gravitational force when the distance between two objects increases?

• It increases
• It decreases
• It stays the same
• It becomes zero

Which of the following is a result of the gravitational force between the Earth and the Moon?

• Tides
• Wind
• Rainbows
• Earthquakes

What is the Earth's gravitational field?

• The space where gravity affects objects
• The area where magnetic forces are strong
• The region where light travels
• The space where sound can be heard

What do magnetic field lines represent?

• The strength of gravity
• The direction of magnetic forces
• The speed of light
• The temperature of a magnet

What is the primary characteristic of unlike magnetic poles?

• They repel each other
• They attract each other
• They do not interact
• They create electricity

What happens when a magnet is divided into two parts?

• It loses its magnetic properties
• Each part becomes a new magnet
• It creates a stronger magnet
• It becomes non-magnetic

What is static electricity?

• Electricity that flows continuously
• Electricity generated by rubbing materials together
• Electricity produced by batteries
• Electricity from power plants

What is the relationship between mass and weight?

• Mass is the same as weight
• Weight is the gravitational force on mass
• Mass changes with location
• Weight does not depend on gravity

How is weight calculated?

• Weight = Mass + Gravity
• Weight = Mass x Gravity
• Weight = Mass - Gravity
• Weight = Mass / Gravity
