Forces Flashcards
1
Q
Weight
A
The force due to gravity between an object and the earth
2
Q
Normal reaction
A
Force that’s perpendicular to its surfaces, when two surfaces are touching and apply a contact force on each other
3
Q
Tension
A
When a spring is stretched there is internal tension force
4
Q
Thrust
A
When a spring is compressed there is an internal thrust force
5
Q
Resistance and friction
A
When two objects are moving in opposite directions there are forces that oppose the motion
6
Q
Newtons second law
A
F=ma
Resultant force= mass x acceleration
7
Q
Newtons first law
A
Resultant force = forces in direction travelling - forces in opposite direction
