Antworten
-
It accelerates
-
It decelerates
-
It stays the same
Frage 2
Frage
The acceleration of a car depends on..
Antworten
-
speed it was traveling and road surface
-
air resistance applied and mass of car
-
size of resultant force and mass of car
Frage 3
Frage
What can an object best accelerate?
Antworten
-
when the force is greater but mass is smaller
-
when the mass is greater and the force is greater
-
when the force is smaller but the mass is greater
Frage 4
Frage
what is newtons second law of motion?
Antworten
-
force (N) = Mass (kg) + acceleration (m/s squared)
-
force (N)= Mass (kg) x acceleration (m/s squared)
-
force (N)= Mass (kg) - acceleration (m/s squared)
Frage 5
Frage
when investigation force and acceleration what must you keep the same?
Antworten
-
Force
-
Mass
-
Acceleration
Frage 6
Frage
How do you work out Acceleration (m/s squared) ?
Antworten
-
change in velocity (m/s) divde by time (s)
-
change in velocity (m/s) x time (s)
-
change in velocity (m/s) - time (s)
Frage 7
Frage

(acceleration= change in velocity divided by time)
Antworten
-
5m/s sqaured
-
4 m
-
2 m/s squared
