Q: What is the difference between speed and velocity in physics?

A: Speed is a scalar quantity that measures how fast an object is moving, while velocity is a vector quantity that measures both the speed and direction of an object's motion. Speed is the magnitude of velocity.

What is the formula for the force of gravity between two objects?

$$F = Gm_1m_2/r^2$$

where:

- F is the force of gravity (in Newtons)

- G is the gravitational constant (6.674 × 10^-11 N m^2 kg^-2)

- m_1 and m_2 are the masses of the two objects (in kilograms)

- r is the distance between the centers of the two objects (in meters)
