What is friction?
Friction is the force that accelerates motion.
Friction is the force that attracts objects.
Friction is the force that causes objects to float.
Friction is the force that resists motion.
Name the two types of friction.
dynamic friction and rolling friction
sliding friction and rolling friction
fluid friction and air friction
static friction and kinetic friction
Which type of friction occurs when an object moves through a fluid?
Static friction
Rolling friction
Fluid friction or drag
Kinetic friction
Which type of friction occurs when an object is at rest?
Dynamic friction
Kinetic friction
Static friction
Sliding friction
What is static friction?
Static friction is the force that resists the initiation of sliding motion between two surfaces that are in contact and at rest relative to each other.
Static friction is the force that causes objects to move smoothly without resistance.
Static friction is the force that increases as objects move faster.
Static friction is only present in liquids and gases, not solids.
What is kinetic friction?
Kinetic friction is the force that increases the speed of objects in motion.
Kinetic friction is the force that helps objects move smoothly without resistance.
Kinetic friction is the force that opposes the relative motion or attempts of motion between two surfaces in contact when they are moving past each other.
Kinetic friction is the force that causes objects to attract each other.
How does friction affect the motion of an object?
Friction opposes the motion of an object by acting in the opposite direction.
Friction has no effect on the motion of an object
Friction accelerates the motion of an object
Friction changes the color of an object
Give an example of rolling friction.
A ball rolling on grass
A bike on a sidewalk
A skateboard on a ramp
A car moving on a road
Explain the concept of fluid friction.
Fluid friction is the energy lost by a fluid due to its viscosity.
Fluid friction is the resistance to an object's motion through a fluid.
Fluid friction is the force exerted by a fluid on an object at rest.
Fluid friction is the attraction between two objects submerged in a fluid.
How can friction be reduced?
Increasing friction, using rough surfaces, applying more pressure
Using lubricants, polishing surfaces, or using ball bearings
Which device can be used to measure force?
What is the unit of force?
gram (g)
centimeter (cm)
newton (N)
liter (L)
