Intro to kinetics/newtons laws Flashcards
1
Q
Define what a force is
A
- Is a push or pull on an object
- Has magnitude and direction (a vector)
- Generally ignore internal forces that produce external force
- They can cancel eachother out
- Define your object system
- SI Units = Newtons = N = 1 kg
- m/s2
2
Q
how do you calculate summing net
forces.
A
Fnet = F1 + F2 + F3 ….
3
Q
Identify and label the type of forces at play in a defined
system
A
Contact/Mechanical Forces:
- Normal
- Friction
- Tension
- Spring
Field Forces:
- Gravity
- Electromagnetic
- Strong nuclear
- Weak subatomic
4
Q
Draw and identify correctly draw free-body diagrams
A
5
Q
State and define the three universal laws (Newton’s
laws) that govern all forces and their interactions.
A
