Forces and acceleration Flashcards
1
Q
what is acceleration
A
measure of how quickly it speeds down, slows down or changes direction
- gradient is used to find the acceleration
2
Q
what is the equation for acceleration
A
acceleration(m/s^2) = final - initial velocity(m/s) / time taken (s)
3
Q
state newtons second law
A
An objects acceleration is directly proportional to the resultant force acting on it and inversely proportional to its mass
4
Q
what is the equation for force
A
force(N) = mass(kg) x acceleration(m/s^2)
5
Q
what is inertial mass
A
describes how difficult its to change an objects velocity
given by ratio of force over acceleration
