What is the definition of relative position?
The speed at which an object moves
The change in an object's position in reference to another object
The force that acts when two surfaces rub against each other
The amount of space covering the outside of a three-dimensional shape
What is the meaning of frame of reference?
The speed and direction of an object
The tendency of an object in motion to stay in motion or an object at rest to stay at rest
An object to which you can compare an object's position
A force that acts when two surfaces rub against each other
What does speed measure?
How fast an object's position changes
The speed and direction of an object
The force that acts when two surfaces rub against each other
The amount of space covering the outside of a three-dimensional shape
What is velocity?
The change in an object's position in reference to a second object.
An object to which you can compare an object's position.
How fast an object's position changes.
The speed and direction of an object.
What is force?
The change in an object's position in reference to a second object
An object to which you can compare an object's position.
How fast an object's position changes.
Any push or pull.
What is friction?
The change in an object's position in reference to a second object.
An object to which you can compare an object's position.
How fast an object's position changes.
A force that acts when two surfaces rub against each other and slows them down.
What is gravity?
The change in an object's position in reference to a second object.
An object to which you can compare an object's position.
How fast an object's position changes.
A force which makes objects pull toward each other or toward the center of the earth.
What is acceleration?
The change in an object's position in reference to a second object.
An object to which you can compare an object's position.
How fast an object's position changes.
When an object speeds up, slows down, and changes direction.
What is inertia?
The change in an object's position in reference to a second object.
The change in an object's position in reference to a second object.
How fast an object's position changes.
The tendency of an object in motion to stay in motion or an object at rest to stay at rest.
What is surface area?
The change in an object's position in reference to a second object.
An object to which you can compare an object's position.
How fast an object's position changes.
The amount of space covering the outside of a three-dimensional shape.
What are the types of motions?
Straight line, curved path, back and forth.
Gravity, inertia, friction, magnetic force, etc.
Sliding, rolling, and static.
Weight or mass and the distance between two objects.
Which type of friction is the strongest?
Sliding friction.
Rolling friction.
Static friction.
Curved path motion.
What factors determine the pull of gravity between two objects?
Weight or mass and the distance between the two objects.
The force of friction.
The speed and direction of an object.
The amount of space covering the outside of a three-dimensional shape.
How can skydivers fall slower?
By spreading out their bodies.
By increasing their weight or mass.
By reducing their surface area.
By exerting more force.
What happens when forces act in the same direction?
They add up and become stronger.
They subtract and become weaker.
They cancel each other out.
They change the object's shape.
What is the difference between mass and weight?
Mass is the amount of material in an object, weight is a measure of the force of gravity acting on that object's mass.
Mass is the force of gravity, weight is the amount of material in an object.
Mass is the speed of an object, weight is the direction of an object.
Mass is the distance between two objects, weight is the strength of gravity.
What are the units for force?
Meters per second.
Newtons
MIles per hour
kilograms
In what units is speed expressed?
meters per second
newtons
miles per hour
kilograms
In what direction does the force of gravity act?
Vertically, downward.
Horizontally, forward.
upward
sideways
What can a force do to an object?
Change its shape.
Change its color.
Change its weight.
Change its texture.
hat are the three types of friction in order from strongest to weakest?
static, sliding, rolling
rolling, sliding, static
static, gravity, sliding
friction, sliding, rolling
What happens when forces act in the same direction?
They add up and produce a weaker force
They subtract and produce a stronger force
They add up and produce a stronger force
They subtract and produce a weaker force
Why do you need to use force to move a ball up a ramp?
The force of gravity makes the ball move downward
The ball has no friction on the ramp
The ball is too heavy to move on its own
The ramp is slippery
Why is it easier to push an empty grocery cart than one filled with canned goods?
The empty cart has less mass or weight
The empty cart has more friction
The filled cart has less friction
The filled cart has less mass or weight
How do forces affect motion?
Forces can change an object that is standing still by causing it to move
Forces can change an object in motion to speed or change direction
Forces have no effect on motion
Forces can only change the shape of an object
What happens when forces act in the opposite direction?
They add up and produce a stronger force
They subtract and produce a weaker force
They add up and produce a weaker force
They subtract and produce a stronger force
What is the relationship between mass and acceleration?
It takes more force to change the speed of a more massive object.
More mass leads to less force
More mass leads to more resistance
More mass leads to less resistance
