Physics revision
Distance - correct answer ✔Speed x time
Speed - correct answer ✔Distance/time
Time - correct answer ✔Distance/speed
Average speed - correct answer ✔M/s
Distance moved - correct answer ✔M
Time taken - correct answer ✔S
Acceleration - correct answer ✔Change in velocity/time
Thrust - correct answer ✔Increases the velocity of an object
Air resistance - correct answer ✔Decreases the velocity of an object
Torque - correct answer ✔Changes the direction of an object
Force - correct answer ✔Mass X acceleration
Friction - correct answer ✔When two surfaces slide past each other, the
interaction between them produces a force of friction.
, Weight - correct answer ✔Mass X gravitational field strength
Momentum - correct answer ✔Mass X velocity
Energy - correct answer ✔Current X voltage X time
Frequency - correct answer ✔Number of waves passing a certain point per
second
Wavelength - correct answer ✔Distance from any point on one wave to the
same point on the next wave
The angle of incidence... - correct answer ✔is always greater than the angle
of refraction
Wave speed - correct answer ✔Frequency X wavelength
The gradient of a velocity time graph represents - correct answer ✔The
acceleration
When all forces are bakanced - correct answer ✔The resultant force = 0
When all forces are unbalanced he resultant force - correct answer ✔Isn't 0
If you double the resultant force - correct answer ✔You double the
acceleratuon
