What is the relationship between speed, distance and time?

• Speed = distance/time

• Speed= distance x time

• Distance= speed x time

• Speed= time

What is the relationship between velocity , timetaken and accelaration ?

• A = (v-u) / t

• Acceleration = velocity * timetaken

• A= v-t

• Acceleration = change in velocity / time taken

What is the relationship between pressure, force and area?

• Pressure = force * area

• Area = pressure - force

• Pressure= force / area

• Area = force / area

What is the relationship between weight, mass and gravitational field strength?

• Weight = mass / gravitational field strength

• W = mg

• Weight= mass x gravitational field strength

• W =m/g

Density is

State the relationship between work done, power, time taken?

• Workdone= timetaken - power

• Workdone = power - time taken

• Power = workdone / time taken

Velocity = frequency x wavelength

• True

• False

Efficiency = energy converted to the required form / total energy input

• True

• False

Power = workdone /time taken

• True

• False

Thermal energy =

• Mass x heat capacity

• Mass x change in temperature

• Mass x specific heat capacity x change in temperature

• Mass + specific heat capacity/ change in temperature
