Question

why is there a negative sign in newtons universal law of gravity? (1 point)
force is a scalar quantity, and gravity is an attractive force.
force is a vector quantity, and gravity is an attractive force.
force is a vector quantity, and gravity is a repelling force.
force is a scalar quantity, and gravity is a repelling force.

Explanation:

• Force is a vector quantity (has magnitude and direction).
• Gravity is an attractive force. The negative sign in Newton's universal law of gravity indicates the direction of the force (towards the other mass, i.e., attractive).

Answer:

Force is a vector quantity, and gravity is an attractive force.
