8- newtons laws of motion Flashcards
1
Q
what is newton’s first law of motion
A
an object moving with constant velocity will remain at rest or continue moving with a constant velocity unless it is acted upon by a resultant force
2
Q
what is newton’s second law of motion
A
an object which is acted upon by an external force will experience an acceleration which is proportional to the force
3
Q
what is the equation linked to newton’s second law
A
f = ma
4
Q
what is F in newton’s second law equation (f= ma)
A
resultant force
5
Q
what is newton’s third law of motion
A
if object A exerts a force on object B, then object b will exert an equal but opposite force on object A.
6
Q
what are the conditions for newton’s third law
A
- the force has the same magnitude
- acts along the same line but in the opposite direction
- acts for the same amount of time \
- is off the same type of force
- acts on two different objects unlike
