Module 2 Part 3: Momentum Energy and Simple Systems

Question 1

what is momentum

Answer 1

The product of the mass and velocity of an object (p = mv)

Question 2

what is the unit for momentum (2)

Answer 2

kgms⁻¹

newtons-second (Ns)

Question 3

what is the symbol for momentum

Answer 3

P

Question 4

how is momentum changed

Answer 4

a force must be applied

Question 5

what is the equation for change in momentum

Answer 5

ΔP = mΔv

Question 6

what is newtons second law expressed in momentum

Answer 6

f= ΔP/t

Question 7

what is those the law of conservation of linear momentum state

Answer 7

during a collision, the total linear momentum of a system is always conserved (Pᵦₑ𝒻ₒᵣₑ = Pₐ𝒻ₜₑᵣ)

Question 8

what is impulse

Answer 8

when a force acts on an object for certain amount of time causing momentum to change

Question 9

what is the symbol for impulse

Answer 9

I

Question 10

what is the equation for impulse

Answer 10

I = Ft

Question 11

what is the relationship between impulse and momentum

Answer 11

impulse is equal to the change in momentum (ΔP = I)

Question 12

in a graph what is impulse equal to in a force vs time graph

Answer 12

the area under the line
