1
Q
inertia meaning
A
tendency of objects to continue in their state of rest/uniform motion
2
Q
inertial mass
A
the measure of how difficult it is to change the velocity of an object
3
Q
inertial mass equation (rearranged too!)
A
inertial mass = force/
acceleration
force = inertial mass x acceleration
acceleration = force/
inertial mass
4
Q

(in terms of braking force)
A
..the greater the braking force needed to stop the vehicle (in a certain distance)
5
Q
the greater the braking force..
(in terms of deceleration)
A
..the greater the deceleration of the vehicle
6
Q
disadvantages of large deceleration
A
- overheated brakes
- loss of control
