Test Revision Flashcards
1
Q
Weight
A
Mass x gravitational field strength
2
Q
Newtons 1st law
A
An object at rest stays at rest, and object in motion stays in motion with the same speed and in the same direction unless its acted upon by an unbalanced force
3
Q
Balences forces
A
Object keeps doing what its doing
4
Q
Unbalanced forces
A
Acceleration or deceleration
5
Q
Acceleration
A
Acceleration = change in velocity / time taken
6
Q
Gravitational potential energy
A
GPE= m (mass) x gravitational field(10 on earth);x h (height)
7
Q
Force
A
F(N) = mass x acceleration
8
Q
Newtons 2nd law
A
An object will stay at rest or continue to move at a constant speed in the same direction unless acted upon by a resultant force
9
Q
Momentum
A
M ( kg m/s)= mass x velocity
