1. Define average speed using the formula.



- Average speed (v) = distance (d) / time (t)




2. What is the standard unit for mass (m)?



- The standard unit for mass is the kilogram (kg).




3. What is the standard unit for distance (d) or displacement (s)?



- The standard unit for distance or displacement is the meter (m).




4. What is the standard unit for speed (s) or velocity (v)?



- The standard unit for speed or velocity is meters per second (m/s).




5. What is the standard unit for acceleration (a)?

, - The standard unit for acceleration is meters per second squared (m/s²).




6. What is the standard unit for force (F)?



- The standard unit for force is the Newton (N).




7. What is the standard unit for time (t)?



- The standard unit for time is the second (s).




8. What is the standard unit for gravitational field strength (g)?



- The standard unit for gravitational field strength is Newton per kilogram (N/kg).




9. What is the standard unit for moment?



- The standard unit for moment, as specified for Paper 2, is the Newton meter (Nm).

,10. What is the standard unit for momentum (p)?



- The standard unit for momentum, as specified for Paper 2, is kilogram meter per second (kg m/s).




What does the gradient of a distance-time graph represent? ✔️Gradient or the slope gives the speed.



Flat line means stationary, straight line means constant speed, curved line means accelerating




Describe how to investigate the motion of a toy car ✔️- Set a ramp up so that the top of it is a certain


height, h, above the desk, and the other end is fixed in place on the desk.



- Measure the distance the toy car will travel down the ramp using a metre ruler.



- Measure the time taken for the toy car to roll down the ramp using a stop watch.



- As it is difficult to start and stop the watch at exactly the right time, the experiment is repeated five


times so an average time can be calculated.



- Divide the distance by the average time to calculate the average speed of the car.

, - To improve the accuracy of the experiment, light gates connected to electronic timers could be used as


human reaction times will no longer affect the results. We still take multiple readings as the car may not


have been released in exactly the same way each time.



- An electronic timer that reads to more decimal places will give the answer to a greater level of


precision.




Acceleration = ✔️Change in velocity/time taken



a = (v-u) / t




What does the gradient of a velocity-time graph represent?



What does the area underneath the line represent? ✔️gradient = acceleration



flat line = constant velocity



straight lines = constant acceleration (changing velocity)



area under graph = distance travelled
