Total questions: 42
Worksheet time: 37mins
when an object changes its position relative to a reference point.(moves)
Motion
Speed
Acceleration
Position
the speed at one point in time.
Velocity
Instantaneous speed
Average speed
Constant speed
A place or object used for comparison to determine if something is in motion
Velocity
Acceration
Position
Reference Point
how far something has moved
Distance
Displacement
Position
Velocity
is the distance and direction of an object's change in position from the starting point.
Distance
Displacement
Velocity
Acceration
the distance an object travels per unit of time.
speed
distance
displacement
position
No change in speed; no calculation needed
speed
instantaneous speed
average speed
constant speed
location relative to a reference point
distance
position
velocity
speed
describes speed of motion when speed is changing; the total distance traveled divided by the total time of travel.
speed
instantaneous speed
average speed
constant speed
the change in velocity (m/s2)
Speed
Direction
Position
Acceleration
a push or pull
Force
velocity
speed
distance
Forces on an object that are equal in size and opposite in direction; net force = 0
net force
balanced force
unbalanced force
instant foce
pushing with unequal forces in opposite directions, a net force occurs in the direction of the larger force.
balanced forces
net forces
unbalanced forces
instant forces
When two or more forces act on an object at the same time; combined forces.
velocity
displacement
inertia
net force
The tendency of an object to resist any change in its motion. It will keep moving at the same speed and in the same direction unless another unbalanced force acts on it
Inertia
Velocity
Acceleration
Force
the person able to state rules that describe the effects of forces on the motion of objects
Madam Curry
Sir Isaac Newton
Albert Einstein
Orville Wright
Newton's first law of motion states...
that an object in motion will stop motion unless an unbalanced net force acts on it.
that an object in motion will stay in motion unless an unbalanced net force acts on it.
The first law of motion says that a moving object tends to keep
force
speed
distance
moving
If there was no friction, objects in motion would stay in motion forever.
true
false
Why is it harder to push a cart full of bricks than a cart full of feathers?
The bricks have more friction than the feathers.
The feathers have more friction than the bricks.
The bricks have more weight/mass than the feathers.
The feathers have more weight/mass than the bricks.
You calculate speed by dividing the distance moved by...?
Time
Velocity
Acceleration
Vector
What do you need to know about an object to calculate its velocity?
Speed and time
Speed and direction
Speed and velocity
Time and direction
Which of these objects is NOT accelerating?
A plane slowing down to land
A rocket taking off into space
A hiker moving at the same speed for hours
A rollerblader heading downhill
