(speed = distance ÷ time)
Which investigation will best test the effects of gravity on moving objects?
pencils falling from the same height
balloons floating upward from the same height
a bicycle speeding up on a flat surface
a ball slowing down on a flat surface
Which best describes the role friction plays in the operation of a car?
Friction makes a car go faster.
Friction keeps a car from stopping.
Friction turns the car in a new direction.
Friction helps a car slow down and stop.
Carey left a bowling ball and kickball outside on a windy day. Which best explains why the kickball moved but the bowling ball did not?
The kickball has less mass so it was easier to move.
The force of gravity acting on the bowling ball is greater.
The mass of the kickball is greater so it is easier to move.
The force of gravity acting on the kickball is greater.
Juan and Angela roll toy cars on a sidewalk. What make the cars finally come to a stop?
friction
electricity
inertia
gravity
Which material should be used on a bicycle ramp to increase friction?
sand
oil
water
liquid soap
Which will most likely increase the speed of an object?
Applying a slower force
Applying a faster force
Applying a weaker force
Applying a stronger force
Why would you need more force when riding a bike up a hill than down a hill?
The mass of a bicycle is less when riding up a hill.
The mass of a bicycle is greater when riding up a hill.
More force is needed to keep a bike going up a hill while gravity is pulling it down the hill.
Two cars, a heavier car and lighter car, are pushed with equal force, and are affected by the same amount of friction.
Which best describes the effect on the distance the cars will
move?
The lighter car will travel a longer distance because it has more mass.
The heavier car will travel a shorter distance because it has more mass.
The lighter car will travel a shorter distance because its wheels will roll more quickly.
The heavier car will travel a longer distance because its wheels will roll more slowly.
Which of the following will require more foce to move?
2 kg ball
20 kg ball
200 kg ball
2,000 kg ball
Which could cause a ball rolling in a straight line to change direction?
a change in the mass of the ball
a change in the speed of the ball
a change in the volume of the ball
a change in the forces acting on the ball
A train is moving along a track. If the forces acting on the train are balanced, how will its motion be affected?
Change direction
Continue, unchanged
Speed up
Stop
The tendency of an object to stay in motion or at rest until a force acts upon it is
inertia
gravity
speed
frame of reference
Popping popcorn on a hot stove is heat transfer through...
conduction
convection
radiation
condensation
Sarah boiled some water to cook spaghetti. The water boiled because of
conduction
convection
radiation
transpiration
Which best explains why burning leaves is a chemical change?
The leaves emit light during the change.
The temperature of the leaves increases.
The shape of the leaves changes.
The leaves turn to ash and gas as smoke is released
Which lists some effects of El Niño?
warmer temperatures and more rain
warmer temperatures and less rain
cooler temperatures and less rain
cooler temperatures and more rain
Which has the greatest effect on wind speed?

It will produce no precipitation.
It will produce some precipitation.
It will produce intense thunderstorms.
It will produce clear skies and sunny weather.
On a cold, cloudy day, the local weather forecaster predicts that a high-pressure system will be moving into the area in the next 24 hours.
Which weather conditions will this system most likely bring to the area?
hot
snowy
sunny
stormy
