How can an object accelerate if kinetic friction is equal and opposite to horizontal force which would mean it has a net force of zero?

It wouldn't accelerate. It would move at a constant velocity due to its tendency to keep moving (inertia) and friction being canceled out by the horizontal force.

How is friction good and bad?
Friction is good because it provides traction. Friction is necessary for people to stand, or for vehicles to accelerate or break. Friction can also be used to convert kinetic energy to heat or electrical energy. Friction can be bad because kinetic energy is can be lost to friction.
What is the difference with static friction and kinetic friction?
static friction is the friction between two bodies they are in contact. And another sliding over the other. Kinetic friction is the friction between two bodies they are rolling .And that force is opposite to the rolling angle
How can the work-kinetic energy theorem explain why the force of sliding friction reduces the kinetic energy of a particle?
Work = change in Kinetic Energy Because friction acts in the opposite direction of the motion of an object, kinetic energy must be decreased in order to maintain the above equation. Friction opposes motion. Friction converts the kinetic energy of a particle into heat and sound.
How the direction of the force of kinetic friction is related to the direction of an of an objects motion?
Friction always acts opposite to the direction of motion.
How does the direction of the force of kinetic friction is related to the direction of of an objects motion?
Friction always acts opposite to the direction of motion.
When is kinetic friction a good thing?
It involves the opposite sex I'll give you that much
What is the coefficient of kinetic friction between the 13.0kg wooden crate and the horizontal force of 31N of the floor?
.419 .419
Why it is easier to roll a barrel on road than to pull it?
When we roll a barrel on the road, rolling friction acts in the direction opposite to the direction of rolling. In case of pulling, kinetic friction acts opposite to the direction in which the barrel moves. The coefficient of rolling friction is almost always less than the coefficient of kinetic friction. So therefore, in layman's terms, rolling friction is less than kinetic friction, therefore less resistance is faced by the barrel while rolling.
The direction of kinetic friction is always?
against motion For example, if I push a box to the left, kinetic friction is going to the left.
Which type of kinetic fiction is usually greater sliding kinetic friction or rolling kinetic friction?
Sliding Kinetic Friction is usually greater than Rolling Kinetic Friction. Sliding Kinetic Friction is caused by two objects being dragged together, providing more opportunity for the objects' microscopic hills and valleys to catch.
What is the forces acting on a car?
kinetic energy from the engine whereas opposite force act on it called friction..
What are the 2kinds of friction?
Static Friction and Kinetic Friction. Static Friction is what friction that slows you down. While Kinetic friction is sliding friction.
