Sample Questions

1multiple correct

According to Newton's universal law of gravitation, the gravitational force between two objects is:

Show answer

Directly proportional to the product of their masses, Inversely proportional to the square of distance between them

Newton's law states that F = GM₁M₂/r². This means force increases with mass and decreases with the square of distance.

2multiple correct

Mass of an object:

Show answer

Remains constant everywhere, Is a measure of inertia

Mass is constant everywhere and measures the amount of matter in an object and its inertia. Weight changes with location, not mass.

3multiple choice

An object's weight on the Moon compared to Earth is:

Show answer

One-sixth

The Moon's gravity is about 1/6th of Earth's gravity, so an object weighs 1/6th of its Earth weight on the Moon.

4multiple choice

Pressure is defined as:

Show answer

Force ÷ Area

Pressure = Force/Area or Thrust/Area. It measures how much force is applied per unit area.
