if a car is traveling on a straight road at 55 miles/hour. Is it speed and/or velocity?
neither
f a car is traveling on a curved road therefore keeps changing direction;it is traveling at a speed of 55 miles/hour. Is it speed and/or velocity?
Velocity
if an object’s direction changes does the acceleration change, even if the speed doesnt change?
yes
When a object is resting and a force is applied but it is less than the friction will the object more or not?
The object will not move.
When a object is resting and a force is applied but it is more than the friction will the object more or not?
The object will move.
Does the frictional force change due the velocity of an object. (For example if a car turns left will the frictional force change?)
No
Does the frictional force change due the surface area of an object. (For example if a bookshelf is being pushed on its side will the frictional force change if it was being pushed on its bottom?)
No
Does frictional force change due to the weight of an object. (For example if there are 2 cars on a road a light one and a heavy one witch one will slide around more if i were raining?)
Yes
