What else can I help you with?
Is it true or false that friction acts to speed up the motion of an object?
False. Friction acts to oppose the motion of an object, slowing it down. It creates resistance between surfaces in contact, converting some of the kinetic energy into heat.
True or false when an object rolls over a surface the kind of friction that occurs is called round friction?
False. The type of friction that occurs when an object rolls over a surface is called rolling friction, not round friction. Rolling friction is caused by the deformation of the object and surface at the point of contact, which generates resistance that opposes the motion of the object.
What is the force created when an object rolls over a surfaces?
The force created when an object rolls over a surface is called rolling friction. This force opposes the motion of the object and is responsible for slowing down the rolling motion. Rolling friction is generally lower than static or kinetic friction for sliding objects.
When an object over a surface the kind of friction that occurs is called friction?
false
True or false the force needed to overcome kinetic friction is useally greater than that needed to overcome static friction?
False. The force needed to overcome static friction is typically greater than that needed to overcome kinetic friction. Static friction is the resistance to motion when an object is at rest, while kinetic friction is the resistance to motion when an object is already in motion. Static friction requires more force to overcome because it is necessary to break the initial "stickiness" between the surfaces.

Does friction speed up an object?
Friction does not speed up an object; it creates drag and slows it down.

Is The force needed to overcome static friction usually less than that needed to overcome kinetic friction.?
True -It's "False"!
what; forces cause SOME changes in motion true or false?
True. Changes in motion are caused by forces acting on an object, such as gravity, friction, air resistance, and applied forces. These forces can either speed up, slow down, change the direction, or stop the motion of an object.
Air resistance is a type of friction True or False?
Air- resistance is basically a type of friction between an object and the air
When an object rolls over a surface the kind of friction that occurred is called round friction True or false?
false it is rolling friction
Kinetic frictions is the frictional force needed to start an object at rest into motion?
false. Kinetic friction is the friction acting upon a moving object. It would be the frictional force against you if you pulled a box across a table. Static friction is the frictional force needed to overcome to get an object at rest into motion.
A force will make a moving object slow down or stop true or false?
True. A force acting in the opposite direction to the motion of a moving object will slow it down or stop it. This is known as friction or drag.
