Which one's wrong?
v = u + at
v 2 = u 2 + 2as
s = ut + at2 / 2
s = u + v /2
These moments would be in equilibrium when...
d1 + f1 = d2 +f2
d1 - f1 = d2 - f2
d1 x f1 = d2 x f2
d1 x f2 - d2 x f2
What is an elastic collision?
kinetic energy is conserved, energy transferred to surroundings
kinetic energy is not conserved, no energy transferred to surroundings
kinetic energy is not conserved, no energy transferred to surroundings
kinetic energy is conserved, no energy transferred to surroundings
What is an inelastic collision?
kinetic energy is not conserved, energy is transferred to the surroundings
kinetic energy is not conserved, no energy transferred to surroundings
kinetic energy is conserved, no energy is transferred to surroudnings
kinetic energy is conserved, energy transferred to surroudings
Spring constant is reduced in series because both springs experience the same force and have the same extension.
True
False
Spring constant is decreased in parallel because the extension of each spring is half the extension of a normal spring.
True
False
How do you work out Young Modulus
tensile stress x tensile strain
tensile stress / tensile strain
tensile strain / tensile stress
tensile strain + tensile stress
Which one of these represents Hookes law?
A
B
C
D
Which of these is Newtons Third Law?
f = ma
every action has an equal and opposite reaction
an object will be stationary or in equilibrium unless it is acted upon by an external force
Which of these is Newtons Second Law?
every action has an equal and opposite reaction
an object will remain stationary or in equilibrium until acted upon by an external force
f = ma
