What happens to the kinetic energy and braking distance of a car when it brakes?
Is proportional to the speed squared (quadruples)
1 of 7
Electric windows are a safety feature. How can electric windows help prevent a crash?
Quicker and easier to open and close the window
2 of 7
When an object is dropped why does its speed increase until it reaches terminal speed?
The weight of the object is greater than the drag/air resistance acting against it
3 of 7
In a speed-time graph what can be calculated from the area from the area under the line?
Distance travelled
4 of 7
When an object's weight is greater than its drag, what happens to the acceleration of free-fall acting on the object as it falls?
Stays the same
5 of 7
When an object is at terminal speed what happens to the object's potential energy and what does it do?
Decreases as it works against the friction between the object and air
6 of 7
What happens to the kinetic energy of an object at terminal speed?
Remains constant
