Question

if you push on an object and slide it across a surface, the force of friction will ____ the motion. friction acts in a direction that is __ to the surface on which the object slides, and __ to the direction in which the object slides. __ friction opposes the start of an objects motion, and __ friction opposes continuing the motion when the object is already in motion. of these two forces, __ friction is greater. the amount of friction can be calculated using the equation __. the constant in the equation is called the ____. word bank: oppose sliding static ff = μfn coefficient of friction static opposite parallel

Explanation:

Friction is a force that opposes motion. When an object slides, friction acts parallel to the surface and opposite to the motion direction. Static friction opposes the start of motion, sliding (kinetic) friction opposes continuing motion. Static friction is greater. The formula \(F_f=\mu F_n\) is used, with \(\mu\) being the coefficient of friction.

Answer:

Blank 1: oppose
Blank 2: parallel
Blank 3: opposite
Blank 4: static
Blank 5: sliding
Blank 6: Static
Blank 7: \(F_f = \mu F_n\)
Blank 8: coefficient of friction
