Physics Unit 5 Review

Front

What happens to the gravitational force if the distance between two objects is halved?

Back

The gravitational force becomes 4 times bigger.

Front

What states that "every object in the universe attracts every other object"?

Back

Law of Universal Gravitation.

Front

What are the two factors affecting the magnitude of the force of gravity between two objects?

Back

Mass and distance.

Front

The force of gravity is directly proportional to which of the following?

Back

Mass.

Front

Calculate the gravitational force between two objects when they are 0.750m apart. Each object has a mass of 5.00kg.

Back

2.96x10^-9 N.

Front

What is the formula for calculating gravitational force?

Back

F = G * (m1 * m2) / r^2, where G is the gravitational constant.

Front

What is the gravitational constant (G)?

Back

G = 6.674 × 10^-11 N(m/kg)^2.

Front

How does increasing the mass of one object affect the gravitational force?

Back

Increasing the mass increases the gravitational force.

Front

How does increasing the distance between two objects affect the gravitational force?

Back

Increasing the distance decreases the gravitational force.

Front

What is the relationship between weight and mass?

Back

Weight is the force of gravity acting on an object's mass.
