1)What is meant by action and reaction pairs of forces?

2)What are the units of a newton?

# data[].attributes.body
Acceleration-The rate at which velocity is changing

# data[].attributes.body
For every action, there is an equal and opposite reaction.

1)

TRUE or FALSE:

An object which is moving rightward has a rightward force acting upon it.

2) According to Newton's third law, every force is accompanied by an equal and opposite reaction force. The reason that these forces do not cancel each other is ____.

# data[].attributes.body
Force- A push or pull exerted on an object

# data[].attributes.body
1) If the forces acting upon an object are balanced, then the object

2)__________ is the tendency of an object to resist changes in its state of motion.

# data[].attributes.body
Motion-the action or process of moving or being moved.

Inertia- the resistance of any physical object to any change in its state of motion

Friction-the force resisting the relative motion of solid surfaces, fluid layers, and material elements sliding against each other.

# data[].attributes.body
The acceleration of an object as produced by a net force is directly proportional to the magnitude of the net force, in the same direction as the net force, and inversely proportional to the mass of the object.

An object at rest will remain at rest unless acted on by an unbalanced force. An object in motion continues in motion with the same speed and in the same direction unless acted upon by an unbalanced force.
