If the force acting on the objects is constant Wich statement about interim and acceleration is supported by the data
A. An object with less mass has less intertia which causes it to speed up less quickly.
B. an object with less mass has more intertia which causes it to speed up more quickly
C. an object with higher mass has less intertia which causes it to speed up more quickly
D. an object with higher mass has more intertia which causes it to speed up less quickly
D. An object with higher mass has more inertia which causes it to speed up less quickly.

why does the disc fall straight down into the glass when we quickly pull the index card away.
A. equilibrium
B. intertia
c. kinetic friction
D. static friction
B. inertia
a student is riding the school bus. The bus stops as the driver applies the brakes. Which of the statements best describe this situation.
A. the buss is graining energy because of friction
B. a force is changing the motion of the bus.
C. the school bus does not loose or gain kinetic energy
D, There is no force acting on the bus so it stops moving
B. A force is changing the motion of the bus.
A pitcher throws a baseball to the cather. the balls path begins as a straight line, and then its patch curves towards the ground. Which two forces are acting on the baseball?
A. electricity and friction
B. gravity and friction
C. intertia and magnetism
D. nuclear and intertia
B. Gravity and friction.
Interia is....
A the resistance of an object to change its motion
B a moving objects speed and direction
C an object's motion
D a force that acts on a resting object
A. The resistance of an object to change its motion.
you are sitting in a stopped bus. when the bus starts moving forwards, you appear to move backwards relative to the bus, which statement best explains this observation.
The bus moves forwards, while intertia keep you in place.
the motion of the bus creates an unbalanced backward force on you.
the force of inertia on you balances the force from the motion of the bus.
intertia prevents the force of the buss from acting on you
