1
New cards
non equilibrium situation
the forces acting on the object are not balanced, meaning that the sum of the forces is not equal to zero.
2
New cards
Free Body Diagrams
depict forces acting on an object using arrows
3
New cards
gravitational force
keeps the earth and other planets in orbit around the Sun.
4
New cards
F=ma
Equation for acceleration (Newton’s Second Law)
5
New cards
normal force
The ________ is perpendicular to the surface and acts to support the weight of the object.
6
New cards
equilibrium situation
the forces acting on the object are balanced, meaning that the sum of the forces is equal to zero.
7
New cards
normal force
contact force perpendicular to the surfaces in contact
8
New cards
Newton's 1st Law (Principle of Inertia)
An object at rest stays at rest, and an object in motion stays in motion with a constant velocity unless acted upon by an external force
9
New cards
Newton's 2nd Law
The acceleration of an object is directly proportional to the force acting on it and inversely proportional to its mass
10
New cards
Newton's 3rd Law
For every action, there is an equal and opposite reaction
11
New cards
Types of friction
sliding friction and rolling friction
