continue with the same speed
increase its speed
decrease its speed

An object is moving with a constant speed, then the sum of forces is equal to
ΣF=0
ΣF = m.a
The force is a
vector
scalar
The magnitude of the frictional force is
negative
positive
always zero

The frictional force of a 1.2Kg-block (μ=0.25) is
Take g=10 N/Kg
f=4N
f=3N
f=2N
f=1N
If the friction < applied force,
then the object's speed
increases
decreases
remains constant
is zero
If the friction > applied force,
then the object's speed
Increases
Decreases
Remains constant
is zero
If the friction = applied force,
then the object's speed
Increases
Decreases
Remains constant

greater
less
equal
