1
Q
types of forces
A
contact force - frictional & elastic force
non-contact force - gravitational & magnetic force
2
Q
frictional force
A
forces that opposes motion between 2 surface in contact
3
Q
elastic force
A
when a elastic material is stretched or compressed, it resists the change in shape by exerting force in opposite direction
4
Q
gravitational force
A
attracts 2 object towards each other and pulls to the center
5
Q
magnetic force
A
force exerted by a magnet & magnetic material
6
Q
effects of force
A
turning effect & changes in size/shape of object
7
Q
turning effect
A
force applied on an object cause a turning effect on point (pivot)
8
Q
change in size or shape in object
A
the transfer of energy between objects may cause change in size or shape in object
