Flashcards in Forces Deck (15):
What is displacement?
Displacement is the two different distances in different directions minus each other
How do you represent constant speed?
By doing a straight line without any slopes on top of the bottom line
What is the SI unit for speed?
What is acceleration?
Velocity divided by time taken
How do you know what is the greatest positive speed?
It depends on where it starts and how far it moves in a certain time
What are examples of scalars?
What are the examples of vectors?
Non contact forces
What is Newton's second law?
The acceleration of an object is:
1)Directly proportional to the resultant force of an object
2)Inversely proportional to the mass of an object
Force=Mass x acceleration
What is stopping distance?
Thinking distance + braking distance
What is thinking distance?
Thinking distance is how far you've travelled during your reaction time
What is braking distance?
How far you've travelled when you start to break
What are the things that affect thinking distance?
.rush/in a hurry
