What does the gradient of a distance-time graph represent? - CORRECT ANSWERS 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 - CORRECT ANSWERS - 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 = - CORRECT ANSWERS 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? - CORRECT ANSWERS gradient =
acceleration
flat line = constant velocity
straight lines = constant acceleration (changing velocity)
area under graph = distance travelled
(final speed)² = - CORRECT ANSWERS (initial speed)² + (2 x acceleration x distance)
v² = u² + (2 x a x s)
(This equation is given to you)
