Examkrackers Mcat Physics 1

Front 1

Two common triangles on MCAT?

Back 1

5-4-3

13-12-5

also 30-60-90 triangle

Front 2

Uniform accelerated motion equations?

Back 2

∆X = Vot + (1/2)(a)(t^2)

Vf = Vo + at

V^2 = Vo^2 + 2a∆x

Front 3

Average Velocity =

Back 3

Average Velocity = (Vf + Vo) / 2

Average velocity is independent of the path taken while instantaneous speed/velocity are

Velocity = displacement/time

Also, Displacement = V(avg)*t!!!

Front 4

Peak height of a projectile?

Back 4

Vo sin(theta) = sqrt(2gh)

Vo can be used as Vf to find final velocity of projectile

Front 5

For a projectile without air resistance the range is maximized at an angle of

Back 5

45

Front 6

Time to reach peak height = ?

Back 6

1/2 total flight time

Vertical velocity dictates time of flight

Front 7

Newtons Law of Universal Gravity

Back 7

F = GMm / (r^2)

Front 8

Inclined Plane:
Force due to gravity?
Normal Force?

Back 8

Force due to gravity = mgsin(theta)

Normal Force = mgcos(theta)

Front 9

Normal force of a curved ramp?

Back 9

mgcos(theta) + mv^2/r

Front 10

Centripetal acceleration?

Force?

Back 10

a = v^2/r

F = ma = mv^2/r

Front 11

Projectiles: Horizontal v? Vertical v?

Acceleration?

Back 11

Horizontal V is constant (vcosø), vertical isn't (vsinø).

Acceleration is constant -10m/s^2

Front 12

Factors of objects that change air resistance?

Back 12

Velocity, surface area, shape.

Mass changes the effect of air resistance, but doesn't change air resistance.
