A force of attraction between objects that is due to their masses and the distance between them.
force
gravity
static friction
fluid friction
A friction force that acts on objects that are not moving
fluid friction
static friction
sliding friction
F=ma, a=F/m, m=F/a
Newton's Second Law of Motion
Newton’s First Law of Motion
Newton’s Third Law of Motion
A push or pull exerted on an object.
acceleration
inertia
force
position
A force that opposes the direction of motion of an object as it slides over a surface, slowing the motion
fluid friction
sliding friction
static friction
Which describes the gravitational force of a planet?
large and pulls objects toward itself
small pulls objects toward itself
large and pushes objects away from itself
small and pushes objects away from itself
Which pair of object has the LARGEST gravitational force?
A marble and a car
marble and a baseball
car and bowling ball
There is no gravitational force between any of these objects.
Sam is moving heavy furniture by sliding it across the floor. She puts a blanket underneath the furniture. Why did this help her?
The blanket protects the sides of the furniture from bumping into the walls.
The blanket reduces the gravitational force between the furniture and the floor.
The friction is larger between the blanket and the floor than between the furniture and the floor.
The friction is smaller between the blanket and the floor than between the furniture and the floor.
You and your calculator are sitting about 3ft apart. Which best explains why the gravitational force does not cause you to move towards each other?
No gravitational force exists between the two objects because they are not touching.
No gravitational force exists between the two objects because their masses are small.
The gravitational force between the two objects is weak because they are so close.
The gravitational force between the two objects is weak because their masses are so small.
If someone drops a cup, the cup falls to the ground. Why doesn’t the gravitational force between the
person’s hand and the cup keep it from falling?
The cup does not experience any gravitational force because it is not a planet.
The gravitational force between the hand and the cup is so strong that it pushes the cup down.
There is no gravitational force between the hand and the cup, so Earth’s gravitational force pulls
the cup down.
There is a gravitational force between the hand and the cup, but Earth’s gravity is stronger so
Earth’s gravity pulls the cup down.
In which situation is it better to have LOW friction?
a skydiver uses a parachute
a hockey puck slides toward the goal
a ladder leans against the wall
a student walks down a hallway

What is inertia?
a friction force that opposes the motion of an object through a fluid
The tendency of an object to resist a change in motion
total distance divided by total time
What is average speed?
the tendency of an object to resist a change in motion
the forces two objects apply to each other - the action force and the reaction force
total distance divided by total time
What is air resistance?
fluid friction acting on an object moving through the air
the forces two objects apply to each other - the action force and the reaction force
a friction force that opposes the motion of an object through a fluid
Equal forces acting on an object in opposite directions; net force is zero
unbalanced force
net force
static friction
balanced force
The rate at which velocity changes
constant speed
velocity

An object's distance and direction from a reference point= position
True
False
The distance an object travels per unit of time is inertia.
True
False
the rate of change of position in which the same distance is traveled each second = instantaneous speed
True
False
An object at rest stays at rest and an object in motion stays in motion unless acted upon by an unbalanced force= Newton's First Law
True
False
final velocity-initial velocity/time =acceleration
True
False
The amount of matter in an object
