EQ What changes an objects motion Friction and Gravity What happens when you jump on a sled on the side of a snowcovered hill What happens at the bottom of the hill Friction and Gravity Why does the sleds motion change on the side of the hill and then again at the bottom. Universal gravitational constant G667 x 10 11 Nm kg 2 2 EPS 122 Lecture 14 Gravity and isostasy Theory of gravity Gravitational potential Definition The gravitational potential V due to a point mass m at a distance r from m is the work done by th 3 FRICTION The property by virtue of which a resist ing force is created between two rough bodies that resists the sliding of one body over the other is known as friction The force that always opposes the motion of o What do you Remember about Friction?. What do you Remember about Friction?. Friction opposes motion. Friction is dependent on the texture of the surfaces. Friction is dependent on normal force. motion. Wedges . & Screws. ENGR B36 - Statics. Pat Aderhold. 11/24/2014. News & Notes. News & Notes. Today’s Agenda. More friction.... Wedges. Screws. Practice Problems on white board. Review / project time. Friction. Friction is a force that opposes the motion, or tendency of motion, of an object.. Friction is caused . mostly by . the . electromagnetic . interactions of particles within molecules at the surfaces of objects in contact. While these interactions can be rather complex, their combined effects can be reasonably approximated with a decent amount of consistency.. Physics 6A. Prepared by Vince Zaccone. For Campus Learning Assistance Services at UCSB. Friction is a force that opposes the motion of surfaces that are in contact with each other.. We will consider 2 types of friction in this class:. EQ: What changes an object’s motion?. Friction and Gravity. What happens when you jump on a sled on the side of a snow-covered hill?. What happens at the bottom of the hill?. Friction and Gravity. Why does the sled’s motion change on the side of the hill and then again at the bottom?. What factors affect (the size of) friction?. Survey says:. Surface texture. Surface material. Surface area.
