1
Q
Equations for speed
A
Speed= distance/time
2
Q
Distance
A
Speed x time
3
Q
Time
A
Distance/speed
4
Q
Acceleration
A
(Final velocity^2)-(initial velocity^2) = 2 x acceleration x distance
5
Q
Newton’s first law
A
If the resultant force is zero and the object is stationary, the object will remain stationary.
If the resultant force is zero and the object is moving, it will continue to move in the same speed and direction.
6
Q
Newton’s second law
A
The acceleration of an object is directly proportional to the force, and inversely proportional to the mass of the object.
7
Q
Equation to work out force (f)
A
F=m (mass) x a (acceleration)
8
Q
Required practical of using light gates
A
9
Q
Terminal velocity
A
The maximum velocity that an object can attain when it is falling through a fluid, such as air or water.
