Year 11 Paper 1 - Physics

What name is given to a material which allows thermal energy to pass through it easily?

• Thermal insulator

• Thermal conductor

What type of heat transfer happens only in fluids (gas and liquids)?

• Conduction

• Radiation

• Convection

Equation for work done.

• Work done = Force / time

• Work done =Force x distance

• Work done = Force / distance

Equation for power.

• Power = Energy transferred x time

• Power = Energy transferred/distance

• Power = Energy transferred/time

Units for power.

• Joules (J)

• Watts (W)

Units for force

• Newton (N)

• Joules (J)

What is the equation for elastic potential energy?

• Ee=ke²

  Elastic potential energy (J) = spring constant (N/m) x extension² (m)

• Ee=1/2ke²

  Elastic potential energy (J) = 1/2 x spring constant (N/m) x extension² (m)

What charge will an object have if it gains electrons?

• Negative

• Positive

How do objects become negatively charged?

• By gaining electrons

• By losing electrons

What will happen if two objects with similar charges are brought together?

• Attract

• Repel
