Mechanics Flashcards
1
Q
SUVAT EQUATIONS UNITS
A
S = Displacement (M) U = Initial Velocity (m/s) V = Final Velocity (m/s) A = Acceleration (9.81m/s) T = Time (Sec)
2
Q
S SUVAT 🚫^2
A
S = (u+v)t / 2
3
Q
V SUVAT
A
V = U + AT
4
Q
S SUVAT ✅ ^2
A
S = UT + 1/2at^2
5
Q
V^2 SUVAT
A
V^2 = u^2 + 2as
6
Q
Displacement time graphs (Velocity)
A
velocity is given by the gradient.
7
Q
What is Gradient for velocity time graphs?
A
Gradient = change in velocity /change in time = Acceleration
8
Q
Area under the curve (velocity time graphs)
A
Area under the curve is distance travelled
9
Q
Gradient in velocity’s
A
Gradient in velocity time graphs shows acceleration
10
Q
Acceleration time graph Gradient
A
Acceleration time graph Gradient is the change in acceleration
11
Q
Projectiles equation
A
S = UT + 1/2 AT^2
12
Q
Weight
A
Weight = Mass X gravitational 9.81
13
Q
GPE AND KE
A
GPE = M X G X H KE = 1/2 X MV^2
14
Q
Link KE WITH GPE
A
GPE at the top = KE at the bottom
15
Q
Moment
A
Work done = Force X Distance from pivot
