MCAT Physics review Questions

Question 1

Big 5 equation without acceleration

Answer 1

d = ½ (v_i + v_f) t

Question 2

Big 5 equation without displacement

Answer 2

v_f = v_i + at

Question 3

Big 5 equation without final velocity

Answer 3

d = v_it + ½at²

Question 4

Big 5 equation without initial velocity

Answer 4

d = v_ft - ½at²

Question 5

Big 5 equation without time

Answer 5

v_f² = v_i² + 2ad

Question 6

Inertia

Answer 6

Intertia is an objects natural resistance to change in its state of motion

Question 7

Centripetal acceleration formula

Answer 7

a_c = v²/r

Question 8

Centripetal force formula

Answer 8

F_c = ma_c

F_c = mv² / r

Question 9

What happens to kinetic energy when a collision is elastic?

Answer 9

When a collision is elastic kinetic energy is conserved

Question 10

What happens to kinetic energy during an inelastic collision?

Answer 10

During an inelastic collision kinetic energy is not conserved

Question 11

What happens to kinetic energy in a perfectly ineleastic collision?

Answer 11

During a perfectly inelastic collision objects stick together after a collision

Question 12

Formula for impulse

Answer 12

Force x time

Question 13

Linear momentum formula

Answer 13

Linear momentum = mass x velocity

p = mv

Question 14

Formula for work

Answer 14

W = Fd cos (ø)

Question 15

Formula for area of a circule

Answer 15

A = πr²

Question 16

Formula for power (there are two)

Answer 16

Power = work / time

Power = energy / time
