7.1 Quizizz Unit #1b Review

A _____________________ shows all of the forces acting on an object.

The total force is the total of all the force acting on the object. For example in the diagram the total force is 7 N to the right. This means the object will accelerate to the right.

______________________________ or the __________________________ is the force of attraction between two objects that is caused by their mass.

• Universal gravitation / Force of Gravity

• Kinetic friction / energy

• Static friction / friction

• Circuit / battery

The ___________________________ the larger the force of gravity is. The smaller the mass the smaller the force of gravity will be.

• smaller the mass

• larger the mass

• smaller the distance

• larger the distance

The ______________________________ are the larger the force of gravity will be. The farther two objects are the smaller the force of gravity will be.

• closer two objects are

• farther two objects are

• more mass

• less mass

_________________________________ is a force that pulls an object towards the center of a circular path when it is moving around another object.

• Centripetal force

• Normal Force

• Force of friction

• Static friction

_________________ is the force of gravity.

________________ = Fg = mxg

g = 10 m/s2
