Forces Flashcards
1
Q
Newton’s First Law
A
An unbalanced force accelerates an object (changes its velocity) this means it.
2
Q
Newton’s Second Law
A
The acceleration on an object is determined by the size of the force and the mass of the object
3
Q
Newton’s Third Law
A
Every action has an opposite and equal reaction
4
Q
How do you find kinetic energy?
A
O.5 x mass x speed^2
5
Q
How do you find mass?(using kinetic energy)
A
Kinetic energy /0.5 x speed^2
6
Q
How do you find speed? (using kinetic energy)
A
square root (kinetic energy/0.5 x mass)
