Exploring the Forces of Gravitation

What does Newton's Law of Gravitation state?

• Every point mass attracts every other point mass with a force proportional to the product of their masses and inversely proportional to the square of the distance between them.

• All objects fall at the same rate regardless of mass.

• The force of gravity increases with distance between objects.

• Gravity only affects large celestial bodies like planets and stars.

How does the gravitational force between two objects change if the distance between them is doubled?

• The gravitational force decreases to one-fourth of its original value.

• The gravitational force doubles in strength.

• The gravitational force remains the same.

• The gravitational force increases to three times its original value.

What is the formula for calculating gravitational force?

• F = m1 * m2 / r

• F = G * (m1 + m2) * r

• F = G * (m1 * m2) / r^2

• F = G * m1 * m2 * r^2

If the mass of an object is increased, what happens to the gravitational force acting on it?

• The gravitational force remains the same.

• The gravitational force increases.

• The gravitational force becomes zero.

• The gravitational force decreases.

Define weight in terms of gravitational force.

• Weight is the mass of an object without any forces acting on it.

• Weight is the total amount of matter in an object.

• Weight is the gravitational force acting on an object, calculated as W = m × g.

• Weight is the force exerted by an object in motion.

How is mass different from weight?

• Mass and weight are the same thing; they both measure gravity.

• Weight is the total volume of an object; mass is its density.

• Mass is the weight of an object; weight is the amount of matter.

• Mass is the amount of matter in an object; weight is the force of gravity on that mass.

What is the weight of a 10 kg object on Earth?

• 100 N

• 98.1 N

• 50 N

• 10 N

What is the acceleration due to gravity on Earth?

• 10.5 m/s²

• 9.81 m/s²

• 9.00 m/s²

• 8.9 m/s²

What happens to an object in free fall?

• The object moves upward at a constant speed.

• The object remains stationary in the air.

• The object experiences a force that pushes it sideways.

• The object accelerates downward at a rate of approximately 9.81 m/s².

How does air resistance affect free fall?

• Air resistance only affects objects with mass.

• Air resistance has no effect on free fall.

• Air resistance increases the speed of the fall.

• Air resistance slows down the fall and can lead to terminal velocity.
