a force that pulls metals towards a magnet
when you look at a magnet
a force that eats magnets
This is an example of ____.
gravity
push
pull
This is an example of what force?
pull
push
gravity
What is the unit to MEASURE force?
Kilogram
Meter
Pounds
Newton
What is acceleration?
transfer of energy to an object
going faster
a change in velocity (speed, direction, or both)
an object remaining in motion or at rest until something changes it
Which type of friction keeps objects from sliding around all over the place
Static Friction
Rolling Friction
Fluid Friction
Sliding Friction
Imagine you decide to jump out of an airplane 🛩
Which force is going to pull you down towards earth
Fluid Friction
Static Friction
Gravity
The wind from the airplane
When you jump out of a plane to go skydiving 🪂 you thankfully have a parachute so you can safely land 🛫. Which answer choice explains why the parachute helps you land safely
While gravity pulls you down very quickly, Air Resistance (fluid friction) pushes back against gravity and your parachute, slowing you down
While gravity pushes you down very slowly, Air Resistance (fluid friction) pulls back against gravity and your parachute, which means you can land safely
When you have a parachute gravity is not able to pull you down as fast as it normally can
The parachute will get caught on something on your way down which will save your life
Which would create more friction?
carpet
metal

grease
powder
all of the above
having streamlined vehicles can reduce friction
true
false
The weight of an object varies with the:
pull of gravity
dimensions of the object
volume of the object
Can Friction be an opposing force?
Yes, it slows objects down until they stop
No, it can't stop objects
Sometimes if the object has no mass
material with _______________ surfaces have less friction
smooth
rough
both
What is static friction?
the friction between two objects that are not moving
friction between a rolling object and the surface that it is rolling on
friction is friction where an object rubs against another surface
friction of something going through any type of liquid or air
What type of friction will slow down the rolling soccer ball?
Fluid
Sliding
Rolling
Static
A contact force is from
objects physically touching
far apart objects
not touching object
always a pull
The more friction that there is, the slower an object will move.
true
false
___________________ is an object's ability to resist a change in motion.
