P10.1 Force and acceleration Flashcards
1
Q
How can you investigate force and acceleration?
A
A newton meter pulling a trolley along a known distance with a constant force - motion sensor can be used to record the velocity of the trolley as it accelerates
2
Q
What does Newton’s second law of motion say?
A
Acceleration of an object is proportional to the resultant
Acceleration of an object is inversely proportional to the mass of the object
3
Q
What is Newton’s second law of motion equation?
A
Resultant Force = Mass x acceleration
4
Q
What is inertia?
A
The tendency of an object to stay at rest or to continue in uniform motion is called inertia
5
Q
How can a velocity of an object increase?
A
If the resultant force is in the same direction as the velocity
