pushes or pulls
I don't know
Forces are measured in
Newtons
grams
metres
millilitres
What happens if forces are balanced?
The object will move left
The object will move right
The object will keep moving at the same speed in the same direction
The object will keep moving in the same direction but slow down
What happens if forces are unbalanced?
The object will changed direction, shape or speed
It will move left
It will move right
It will only slow down
Forces are represented using which shape?
squares
triangles
circles
arrows
When do we see friction?
when we pull something
when one surface slides over another
when we push something
when we lift something
Magnets have
a north pole
a south pole
a north and south pole
a west pole
Like magnetic poles will
repel
attract
stick

Unlike magnetic poles will

What is air resistance?
A type of force
A type of friction
A type of magnet
A type of truck
What is a formula for force?
F = mc
F = ma
F = mb
F = m
In the force formula,
m = mass
a = acceleration
m= mass and a = acceleration
m = mass and b = breadth
When we graph forces of different trials on different surfaces we use,
every answer
the averages of each surface
only the first trial
only the ones that prove the hypothesis
Which surface is likely to cause the least friction?
a rough surface
a smooth surface
a large surface
a small surface
What is an example of a tension force?
a desk pushed across a room
a person walking
a spring being released
a person jumping
Which object will have the most air resistance?
a truck
a sports car
a van
a motorbike
What can we say about the forces of an object that is not moving?
there must only be one force acting on it
The forces must be balanced
the forces must be unbalanced
it must be very heavy
Matter is pulled to the ground by
space
gravity
air
soil
Gravity and friction are two types of
inertia
masses
speed
forces
A push or a pull in a certain direction is known as
motion
force
speed
friction
