Acceleration
Acceleration is the rate of change of velocity. If there is a change in velocity, an object may accelerate in the direction of the unbalanced/resultant force.
The unit for acceleration is metre per second squared
The unit for acceleration is metre per second squared
Force = mass x acceleration
1) Work out the resultant force:
1500N – 500N = 1000N
2) Apply the formula (it is a magic triangle, so you can change the order of the letters depending on what you want to find):
Force = mass x acceleration
Acceleration = Force/Mass
A = 1000/800
A = 1.25 m/s2
*Q: If the total frictional force were to increase to 1500N, what would happen to the car?*
A: The forces would both be 1500N and therefore be BALANCED. When forces are balanced, acceleration is at ZERO. The car would then travel at a CONSTANT/STEADY SPEED.
1500N – 500N = 1000N
