The combination of forces acting on an object is known as the ___ force.
net
the acceleration of an object is directly proportional to the net force acting on it. this means that as the net force acting on an object increases, the acceleration of the object ________.
increases
what is true about force and acceleration?
a net force acting on an object causes acceleration
Two shopping carts of equal mass are pushed by two different people. One cart accelerates three times as fast as the other cart. Describe the forces acting on each cart.
a net force acts on both carts. the net force acting on the cart that accelerates faster is three time greater than the other forces.
For a constant force,how does an increase in an object's mass affects its acceleration?
An increase in the mass will result in a decrease in the acceleration.
What does it mean for quantities to be inversely proportional to one another?
When one quantity increases, the other quantity decreases.
How are mass and acceleration related?
acceleration ~ 1/mass
what quantities are related to Newton's second law?
mass force and acceleration
