A
a push, pull or twist
3
Q
What can forces change in?
A
shape, direction & speed
4
Q
do rough surfaces produce more or less friction?
A
Rough surfaces produce more frictions because of their roughness & hard surfaces which provides more grip to hold on to or stick too.
5
Q
Does friction transform kinetic energy into heat energy?
A
yes, because the more you rub and make more kinetic energy you get more friction created.
6
Q
What do you measure forces in?
A
Newtons (N)
7
Q
What are the two magnetic poles at the ends of a magnet?
A
North (N) and South (S)
8
