Total questions: 50
Worksheet time: 33mins
Motion is defined as a change in (a) .
Motion is a(n) (a) when both distance and direction are included.
(a) is something an observer uses to perceive motion
How far you travel in a given amount of time can be used to calculate your (a) .
The difference between two opposing forces is called the (a) force.
The force that opposes motion between any two surfaces is (a) .
(a) friction makes it possible to walk on a sidewalk without slipping.
Anything that has mass exerts a force of (a) on any other mass.
Newton’s (a) law of motion is also known as the law of inertia.
A stationary object resists movement because of (a)
Inertia is greater when objects have greater (a) .
Newton’s (a) law of motion relates acceleration to force and mass
An object will accelerate only if the net force acting on the object is greater than (a) .
The (a) of an object is equal to its mass multiplied by the acceleration due to gravity.
According to Newton’s (a) law of motion, every action has an equal and opposite reaction.
Very short distances should be measured in kilometers
True
False
Distance is less important than direction in describing motion
True
False
Words that describe direction include back and forth.
True
False
Speed is an example of a vector.
True
False
A horizontal line on a distance-graph represents a speed of zero.
True
False
Distance equals speed divided by time.
True
False
If an object’s speed changes so does its velocity.
True
False
Calculating acceleration is complicated when both speed and direction are changing.
True
False
You are accelerating when you jump up and down on a trampoline.
True
False
The SI unit for acceleration is s2km .
True
False
The SI unit for weight is the pound.
True
False
Forces acting in the same direction are subtracted to yield the net force.
True
False
Stationary objects generally have at least two forces acting on them.
True
False
Static friction is weaker than sliding friction.
True
False
Fluid friction is stronger when an object moves more slowly through a fluid.
True
False
A pebble falls to the ground more quickly than a sheet of paper because the pebble has greater mass.
True
False
The law of universal gravitation was proposed by Isaac Newton.
True
False
Both arrows and cannon balls have projectile motion.
True
False
When you stretch a spring, it resists the change in shape.
True
False
Rubber is an example of an elastic material.
True
False
Newton’s first law of motion applies only to stationary objects.
True
False
It takes more force to start running than to keep running.
True
False
It is harder to stop a 60-kg football player than a 40-kg football player if they have the same velocity.
True
False
An object’s acceleration depends on its mass and speed.
True
False
If you increase the net force acting on an object, its acceleration also increases.
True
False
Newton’s second law of motion applies only to objects that are moving.
True
False
If you know an object’s mass, you also know its weight because mass and weight measure the same thing.
True
False
Newton’s third law of motion describes how forces act in pairs.
True
False
When objects collide, momentum is usually lost.
True
False
The SI unit for distance is the
acre
kilogram
meter
centiliter
If you use an arrow to represent velocity, what does the head of the arrow show?
speed
direction
distance
none of these
Which type of friction do you use when you put on the brakes to stop a bike?
static friction
sliding friction
stopping friction
rolling friction
Why does engine oil help prevent an engine from overheating?
It causes chemical reactions that absorb energy.
It reduces friction between moving parts.
It has a higher melting point than metal.
It makes the engine run more slowly.
Inertia causes a moving object to
keep moving
slow down
stop moving
speed up
You would weigh less on the moon than on Earth because
you would have less mass on the moon.
the moon has weaker gravity than Earth.
the moon has a thinner atmosphere than Earth.
two of these
