The natural resistance of an object to change it's motion is called what?

• velocity

• inertia

• force

• acceleration

What gives an object more inertia?

• more velocity

• less velocity

• more mass

• less mass

Why is mass different from weight?

• Weight is only due to how much matter you are made of and is always the same.

• Mass never changes but weight changes when gravity the attraction of gravity is different.

• Mass is acceleration.

• Weight never changes but mass changes when gravity the attraction of gravity is different.
