Conceptual Physics Newton's Laws
Terms in this set (22)
Newton's First Law
An object at rest stays at rest and an object in motion stays in motion with the same speed and in the same direction unless acted upon by an unbalanced force.
Newton's Second Law
Force = mass x acceleration
Newton's Third Law
For every action there is an equal and opposite reaction
Definition of Mass is:
What is the quantity that is solely dependent upon the inertia of an object?
A push or a pull
A book sliding on a table would be an example of what of force?
A book remaining still on a table would be an example of what kind of force?
What stops a book from coming to a stop when it is sliding on a table?
What two categories of forces exist?
Contact forces, and forces resulting from action-at-a-distance
This is an example of contact force?
Name an example of an action-at-a-distance force:
The direction of the net force on an object is the same as the:
What is the opposite force of a bird pushing air down by flapping its wings?
The air pushes the bird up.
What do you need in order to describe an action-reaction force?
1) Identify the 2 interacting objects
2) Describe each of their actions
a force which is applied to an object by a person or another object
Force of gravity
The weight of an object
the perpendicular contact force exerted by a surface on another object
the force exerted by a surface as an object moves across it or makes an effort to move across it
force that opposes the motion of objects that move through the air
pulling force applied to an object that can make an object stretch
The force exerted by a compressed or stretched spring upon any object that is attached to it
