Chapter 10-2 Friction and Gravity Friction Force of Friction – caused by two surfaces rubbing Strength: depends on 1) how hard the surfaces are pushed together 2) types of surfaces Direction: Opposite to direction of motion Types of Friction Static Friction – friction that acts when an object...
Gravity and Motion Free fall – when the only force acting on an object is gravity. In free fall, the force of gravity alone causes an object to accelerate in the downward direction. All objects in free fall accelerate at the same rate. Air Resistance Air resistance is a type of fluid ...
Newton’s 1st law Remember, an object in motion tends to stay in motion, an object at rest tends to stay at rest unless acted on by an outside force. The 2 most common outside forces on earth are: FRICTION AND GRAVITY Friction: The force that two surfaces exert on each other when t...
*Static..prevents objects sliding WHAT IS FRICTION? (P.49) Friction is a force that resists the motion of two surfaces that are touching. When a moving object comes in contact with another object, friction is the opposing force that slows or stops the moving object. *Static..prevents object...
3.1.2. Dataset 11PI-V1 This dataset was obtained via a lab experiment. The experiment used AA6061 and AA5083 materials. In the FSW experiment, worksheet plates 75 mm wide, 175 mm long, and 6 mm thick were used, and the mechanical properties of the two aluminum alloys are listed in Ta...
The FSW experiment used worksheet plates that were 75 mm wide, 200 mm long, and 6 mm thick. Table 2. Dataset details. Table 3. Mechanical properties of base materials. 2.1.1. Dataset 7PI-V1 The parameters used for FSW were as proposed by Luesak et al. [25]: four continuous ...
