- A.
True
- B.
False
- 13.If you push or pull an object, the MASS / ACCELERATION will change.
- 14.Balanced forces are
- A.
When the forces of an object produce a net force larger than zero.
- B.
When the forces are the same .
- C.
When the forces of an object produce a net force equal to zero.
- 15.Unbalanced forces are
- A.
When the forces of an object produce a net force larger than zero.
- B.
When the forces are the same .
- C.
When the forces of an object produce a net force equal to zero.
- 16.What is net force?
- A.
The combination of all the forces acting on an object.
- B.
The force of a net.
- C.
The added measure of the force in action
- 17.What is Newton's third law?
- A.
Every action has an equal and opposite reaction.
- B.
An object's acceleration depends on the mass of the object and the amount of force being applied.
- C.
An object in motion stays in motion and an object at rest stays at rest until acted upon by an outside force.
- 18.What is Newton's first law?
- A.
Every action has an equal and opposite reaction.
- B.
An object's acceleration depends on the mass of the object and the amount of force being applied.
- C.
An object in motion stays in motion and an object at rest stays at rest until acted upon by an outside force.
- 19.What is Newton's second law?
- A.
Every action has an equal and opposite reaction.
- B.
An object's acceleration depends on the mass of the object and the amount of force being applied.
- C.
An object in motion stays in motion and an object at rest stays at rest until acted upon by an outside force.
