First Law of Motion

Question 1

forces

Answer 1

any push or pull that happens when two objects interacts

cause objects with mass to accelerate

vector quantities

Question 2

contact forces

Answer 2

only exist when objects are touchingn

Question 3

non contact forces

Answer 3

forces that can act over a distance

Question 4

what happens when forces are balanced

Answer 4

netforce = 0
object may be moving but it will not be accelerating

Question 5

what happens when forces are unbalances

Answer 5

netforce is not 0

acceleration will occur

Question 6

first law of motion

Answer 6

an object will not change its motion unless acted on by an external unbalanced force

law of intertia

Question 7

intertia

Answer 7

tendency of an object to resist changes to its motion

larger mass - more intertia
the more intertia, the more force is required to accelerate.
