Learning Assessment I

What is mass?

• The amount of matter in an object
• The force exerted on an object due to gravity
• The gravitational field around an object
• The acceleration due to gravity

What is weight?

• The mass of an object
• The acceleration due to gravity
• The force exerted on an object due to gravity acting on its mass
• The gravitational constant

What does a gravitational field refer to?

• The area around an object where its mass is located
• The area around an object where another object experiences a gravitational force
• The acceleration due to gravity
• The distance between two objects

What determines the strength of a gravitational field?

• The mass of the object and the distance from it
• The volume of the object
• The speed of rotation of the object
• The chemical composition of the object

What is the center of gravity (C.G.)?

• The geometric center of an object
• The point where the weight of the object appears to be concentrated
• The highest point in an object
• The lowest point in an object

Does the center of gravity always lie inside the object?

• Yes
• No

How can you increase the stability of an object?

• By raising its center of gravity
• By lowering its center of gravity
• By decreasing the base of support
• By increasing the mass drastically

Which type of equilibrium means an object returns to its original position after displacement?

• Stable equilibrium
• Unstable equilibrium
• Neutral equilibrium
• Dynamic equilibrium

Which type of equilibrium means an object moves further away when displaced?

• Stable equilibrium
• Unstable equilibrium
• Neutral equilibrium
• Static equilibrium

Which type of equilibrium means an object remains in its new position after displacement?

• Stable equilibrium
• Unstable equilibrium
• Neutral equilibrium
• Dynamic equilibrium
