the resultant force on an object that moves along a circular path. For an object of mass moving at speed v along circular path radius r the F=mv^2/r towards the centre of the circle

Card 7
Front
for a system of interacting objects is the total momentum of the objects remains constant provided no external forces acts on the system.
Back
Card 8
Front
for two point charges Q and q, at distance r apart, the force between the two charges s given by F=Qq/... where Eo is permittivity of free space
Back
Card 9
Front
Oscillations that reduce the amplitude due to the presence of restive forces such as friction and drag

Card 11
Front
the total kinetic energy after the collision is equal to total kinetic energy before
Back
Card 12
Front
at a point in an electric field, is the force per unit charge on a small positively charged object at that point in the fieal
Back
Card 13
Front
at a point in an electric field is the work done per unit charge on a small positively charged objet to move it from infinity to that point in the field
Back

Back
Card 15
Front
a line/surface in a field along which the electric/gravitational potential is at a constant
