According to Newton's 2nd law if you use the same force to push a truck and push a car, Which would have more acceleration and why?
The car will have more acceleration than the truck, because the car has more mass.
The car will have more acceleration than the truck, because the car has less mass.
The truck will have more acceleration than the car, because the car has less mass.
They will both have equal accelerations.
Using Newton's 3rd law what is happening in the picture?
An object at rest stays at rest.
An object in motion stays in motion.
For every action there's an equal and opposite reaction.
Force is equal to mass times acceleration
What two things directly affect the force of gravity?
mass and acceleration
distance and mass
force and mass
distance and time
What's the difference between mass and weight?
mass stays the same, weight changes with gravity.
mass increases with gravity, weight stays the same.
mass decreases with gravity, weight stays the same.
mass stays the same, weight stays the same.
Which pulley has the greatest mechanical advantage?

How does a screw make work easier?
The screw makes work easier because it decreases the distance needed to increases the force needed.
The screw makes work easier because it increases the distance needed and decreases the force needed.
The screw makes work easier because it increases the distance needed and increases the force needed.
The screw makes work easier because it decreases the distance needed and decreases the force needed.
