SP1b Acceleration

Question 1

What is acceleration?

Answer 1

it is the change in velocity per unit of time. It’s a vector quantity, measured in m/s²

Question 2

Describe a laboratory method for determining speed of objects, with the use of light gates

Answer 2

the first light gate starts the timer and the second light gate stops the timer - because it has covered a distance then you can calculate the acceleration or the velocity of an object

Question 3

Estimate the magnitude of everyday accelerations (including gravitational pull)

Answer 3

.car - 3m/s²
.motorbike - 6m/s²
.object falling on earth - 9.81m/s² (10m/s²)
