nonsense! A force is NOT required to keep an object in motion.
According to Newton's 3rd Law, whenever objects A and B interact with each other, they exert forces upon each other.
True
False
Force is a quantity that is measured using the standard metric unit known as Newtons (N).
True
False
Contact Forces: are those types of forces that result when the two interacting objects are perceived to be physically contacting each other.
True
False
Field Forces/Action at a distance Forces: are those types of forces that result even when the two interacting objects are not in physical contact with each other, yet are able to exert a push or pull despite their physical separation.
True
False
An object that has a balanced force cannot be accelerating. True or False
True
False
In order for a force to be unbalanced... the object must be: at rest or moving in a constant motion,
True
False
In order for a force to be unbalanced... the object must be: Accelerating.
True
False
The more Mass, The More Inertia
True
False
Newton's First Law is referred to as the "Law of Inertia"
True
False
(a) can be defined as "mass in motion"
All objects have mass; so if an object is moving, then it has momentum - it has its mass in motion.
True
False
The amount of momentum that an object has is dependent upon two variables: ___________ and _____________. **there is more than one answer**
if the object was made in the U.S.
how much stuff is moving
gravity
the type of objects
how fast the stuff is moving
Momentum depends upon the variables ______ and ______. **there is more than one answer**
gravity
mass
time
acceleration
velocity
Momentum is used as the symbol lower case __.
a
v
c
p
m
From the definition of momentum, it becomes obvious that an object has a large momentum if both its mass and its velocity are large.
True
False
Objects at rest do not have momentum - they do not have any "mass in motion."
True
False
A force acting for a given amount of time will change an object's momentum
True
False
If you get the same number when solving for impulse and solving for momentum then you have ______ _______.
(a)
