Mass is a measure of the force of gravity acting on an object while weight is the measure of the inertia of an object.
Force =
mass x velocity
acceleration x velocity
mass x acceleration
43x 21N
Rolling friction is less than static friction, which is more that sliding friciton
Fluid friciton acting on an object moving through the air is known as what?
air resistance
weight
momentum
mass
When you are swimming, you push through the water, in other words you are applying force to the water, and the water is applying the same amount of force to you. This is an example of fluid friction..
When a ball falls from the roof of a building, it accelerates until it stops accelerating. Why?
It hit the ground
it reached its terminal velocity
projectile motion
gravity stopped
Why does a projectile follow a curved path?
two balls fall with different acceleration
Gravity pulls the object down
the combination of a vi and downward velocity causes the ball to follow a curved path
Mass can effect acceleration
Which if the following are vectors?
velocity
force
gravity
Weight =
mass x air resistance
mass x projectile motion
mass x acceleration due to gravity
kg x m/s
