If Shane and Susan both push on a box with a force of 25 N, but in opposite directions, what will happen to the box?
the box will not move
the box will slide toward Shane
the box will slide toward Susan
the box will be perpendicular to both Shane and Susan
Which of these is a good example of Newton's first Law of Inertia
a ball sits motionless on the ground
a ball gathers speed as it rolls downhill
a ball accelerates as it falls out of the classroom window
a ball slows down after it is kicked through the grass
What must occur to a shopping cart at rest in order to make it roll forward?
A force must be provided to overcome gravity
balanced forces must be acting upon the cart
an unbalanced force applied to the cart pushing or pulling it forward
the unbalanced force acting upon it must be smaller than that of friction
An object that has kinetic energy must be
at rest
stopped
in motion
at an elevated position
What would be an ideal experiment to test how different types of surfaces affect friction?
two objects of equal weight placed on two glass surfaces of equal lengths
two objects of equal weight placed on two glass surfaces of unequal lengths
two objects of equal weights placed on a glass surface and a wooden surface
two objects of different weights placed on two wooden surfaces of unequal lengths
Wind energy is used to rotate the sails of a windmill. The rotating sails have
heat energy
kinetic energy
potential energy
electromagnetic energy
The force that slows down and eventually stops a ball you roll across the pavement is called
kinetic force
friction force
the slow force
potential force
How does an object's mass affect its inertia?
increasing an object's mass decreases its inertia
increasing an object's mass will increase its inertia
there will be no effect on its inertia
decreasing an object's mass will increase its inertia
A book is resting on a table. The book has
kinetic energy only
potential energy only
both kinetic and potential energy
neither kinetic or potential energy
Based on the diagram of a roller coaster track, what statement is true?
a car at point A has the most kinetic energy
a car at point B has the most potential energy
a car at point B has more kinetic energy than the car at point D
a car at point D has more kinetic energy than the car at point B
Which BEST explains why objects fall downward when dropped?
the center of Earth exerts a gravitational pull
Earth's orbit exerts a downward force on the atmosphere
most objects are heavier than the air in Earth's atmosphere
the force between Earth's magnetic poles pulls objects downward
What is one way you could reduce the friction between two surfaces?
carpet the surfaces
put oil on the surfaces
put sand on the surfaces
allow one of the surfaces to rust
Which of these bikers shows potential energy?
the biker on the left
the biker on the right
their potential energy is the same since they are at rest
they do not have potential energy because they are at rest
