When the force of an object increases, so does its _______
acceleration
velocity
mass
inertia
What distinguishes first class levers from both second and third class levers?
The fulcrum is between the load and effort
There is a fulcrum on both sides of the load
Greater effort is required to move the load.
The first class lever is no found in the human body.
Which of the following requires the action of the first class lever in the body?
Jumping
Push-ups
Waving
Nodding
If two runners take the same amount of time to run a mile, they have the same_____
acceleration
force
mass
velocity
Force is based upon both mass and acceleration.
True
False
According to Newton's 2nd law of motion, force is equal to mass times acceleration.
True
False
The load is the pivot point of a lever
True
False
The first class lever is the most common lever in the human body.
True
False
The ankle is a third class lever.
True
False
Swinging a tennis racket against a ball is an example of a third class lever.
True
False
Matter is ______.
the amount of energy contained within an object
a measure of the force gravity exerts on objects
something that has mass and occupies space
a measure of an object's inertial force
What distinguishes mass from weight?
Mass is a measure of the amount of matter in an object, while weight is a measure of the force of gravity on the object.
Weight is a measure of the amount of matter in an object, while mass is a measure of the force of gravity on the object.
Mass is a measure of an object's inertial force, and weight is the force exerted by that object on other objects.
Mass and weight are synonyms and ultimately describe the same principle.
A balance uses small metal weights of known mass to determine the mass of a substance. Where would a balance NOT function correctly?
in a vacuum on earth
on the moon's surface
on the earth's highest mountain
in a zero gravity environment
What is the difference between velocity and acceleration?
Velocity describes an object's position and acceleration describes how fast it moves.
Velocity is how fast an object moves and acceleration is the rate of change in velocity.
Velocity is used to determine the magnitude of force acting on an object, and acceleration isn't.
Velocity is a time-dependent property of an object, while acceleration is not.
What is BEST to say about a runner who is running at a constant velocity?
Their acceleration is positive.
Their acceleration is negative.
Their acceleration is zero.
Their acceleration cannot be determined.
Which of the following is NOT a component of a lever?
Effort
Tension
Fulcrum
Load
What distinguishes the three different classes of levers found in the human body?
Where they are located in the body
how useful they are for performing work
where the components of the lever are located
how many moving parts the lever has
Second and Third class levers both have ____.
the fulcrum between the effort and load
effort applied in the same place
two loads and fulcrum
the fulcrum at one end of the lever
Second and Third class levers are differentiated by ______.
the location of the fulcrum
the location of the load
the presence of multiple loads
the type of fulcrum present
The elbow is considered a third class lever because ______.
the effort is applied further from the fulcrum than the load
the effort is applied closer to the fulcrum than the load
the fulcrum is in the center of the lever
the elbow is used to lift objects
What lever has resistance between the axis (fulcrum) and the force (effort)?
First
Second
Third
Fourth
