Key Concepts
Text
1. Introduction
2. Concepts of Motion
•
How do you visualize motion?
2.5
3. Vectors and Scalars
•
What is a vector and how do you add and subtract them, both graphically and
analytically?
1.6, 1.7,
1.8, 1.9
4. The Language of Motion
•
How do you quantitatively describe motion in terms of position, displacement,
velocity, speed and acceleration?
2.1, 2.2,
2.4
5. Developing a Good Problem-Solving
Strategy
•
What are the four steps to a good problem-solving strategy?
•
What are the physical and pictorial representations?
1.10
6. Kinematics
•
How are position, velocity and acceleration related, both graphically and analytically?
2.3, 2.6,
2.7
7. Motion with Constant Acceleration
•
Continuation of the above concept.
8. Motion in Two Dimensions
•
The kinematic equations are vector equations, so the motion in orthogonal directions
is independent of each other.
3.1, 3.2
9. Projectile and Relative Motion
•
For a projectile, the acceleration is constant and in the downward direction, so the
velocity in the horizontal direction is constant.
•
How is relative motion analyzed?
3.3, 3.6
10. Motion in a Circle
•
For uniform circular motion, the acceleration is constant and always points toward the
center of rotation. This is called centripetal acceleration, and its magnitude is
v
2
/r
.
3.4
11. Force and Motion
•
What is a force, and how do you identify all the forces acting on an object (i.e., the
force body diagram)?
•
An object’s acceleration is proportional to the net
force acting on the object (i.e.,
Newton’s 1
st
and 2
nd
laws – the cause of motion). The proportionality constant is the
object’s mass.
4.1, 4.2,
4.3, 4.4,
4.5, 4.7*
12. Dynamics
•
Continuation of the above concepts.
13. Interacting Objects – Newton’s 3
rd
Law
•
For every force on an object, there is a force on another object
that is equal in
magnitude and opposite in direction (Newton’s 3
rd
law).
•
How do you identify these paired forces?
