Physics paper 1

Question 1

What is the equation that links work done, force and distance?

Answer 1

Work done = Force x distance

Question 2

What is the equation that links Kinetic energy, speed and mass?

Answer 2

Kinetic energy= 0.5 x mass x speed squared

Question 3

How do we calculate GPE?

Answer 3

GPE= mass x height x Gravitational field strength

Question 4

How do we find power using energy transferred and time?

Answer 4

Power = energy transferred/time

Question 5

How do we find power using time and work done?

Answer 5

Power = work done/ time

Question 6

What is the equation that links voltage, power and current?

Answer 6

Power= voltage x current

Question 7

How do we find power using resistance and current?

Answer 7

Power= resistance x current squared

Question 8

What is the equation that links charge flow, current and time?

Answer 8

Charge flow= current x time

Question 9

What is the equation that links charge flow, voltage and energy transferred?

Answer 9

Energy transferred= charge flow x voltage
