Kinematics
This type of quantity is described by both a magnitude and direction.
What is a vector?
F=ma.
What is Newton's Second Law?
FBD is an abbreviation for this very useful method of modeling force analysis of an object.
What is a free-body diagram?
The unit of power breaks down to these next level of units.
What is joules per second?
This property of an object is defined by the equation p=mv.
What is linear momentum?
Distance, speed, and temperature are examples of this type of quantity.
What is a scalar?
What is 9.8m/s^2?
This law states that an object at rest stays at rest, or an object in motion stays in motion, if there is no external force acting on it.
What is Newton's First Law?
The integral of this mathematical process between force and displacement can be used to calculate work.
What is a dot product?
What is impulse?
When using the object model, the size, shape, and internal configuration are ignored. The object may be treated as a ________ _______ with extensive properties such as mass and charge.
What is a single point?
The force exerted on an object by a spring is always directed toward this position in a spring-object system.
What is equilibrium position?
The SI units for this unit are kg*m^2/s^2.
What is a joule?
The work done by a nonconservative force is ______-_______________.
What is path-dependent?
For this type of collision, the objects stick together and move with the same velocity after the collision.
What is a perfectly inelastic collision?
This type of motion is a special case of two-dimensional motion that has zero acceleration in one direction and constant, nonzero acceleration in the second dimension.
What is projectile motion?
This property of an object determines how much an object's motion resists changes when interacting with another object.
What is inertia?
This type of force is represented by the equation F=-kv.
What is a resistive force?
These two conservative forces are the only conservative forces discussed in this course.
What is gravitational force and elastic force?
The total momentum of a system is the sum of the momenta of the system’s _____________ parts.
What is constituent?
This property of an object is the same as measured from all inertial reference frames.
What is acceleration?
This principle states that an observer in a non-inertial reference frame is unable to distinguish between an object’s apparent weight and the gravitational force exerted on the object by a gravitational field.
What is the equivalence principle?
This equation represents the minimum speed required to maintain circular motion for an object at the top of a vertical, circular loop.
What is v=sqrt(g*r)?
Potential energies are only associated with these types of forces.
What are conservative forces?
This law is a direct result of the impulse-momentum theorem applied to systems with constant mass and can be represented by dp/dt.
What is Newton's Second Law?
