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.

Question:
What is the formula for the force of gravity between two objects?
Answer:
$$F = Gm_1m_2/r^2$$
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)
