Check your converter they are known to can out seperate That happened to me in my 1998 Ford Explorer - turned out to be the differential. It started out as a loud thump, thump, thump, then just got louder until it sounded as though something under the vehicle was being dragged and grinded. It was incredibly loud! This all happened in a matter of about 15 minutes.
possibly your wheel bearing is on its way out
Could be a small thing like wheels out of balance 40+ "Noisy Inside Car" bad wheel bearings 30+ mph also decelerating harder to control "Steering wheel wobble "on accelerating / decelerating" "Noisy Inside Car" steering linkage: causes the steering wheel to wobble at 40+ mph decelerating harder to control "Steering wheel wobble "on accelerating / decelerating" My brothers car had the above problems I changed his rear spindle, outer, tie rods, "both were shot" bad bearing "blown bearing"
An unbalanced force is a force that causes a change in the motion of an object, either by accelerating it or decelerating it. When the net force acting on an object is not zero, it will cause the object to move in the direction of the greater force.
could be a center support bearing or a bad engine mount. i would check those first.
It sounds like you have some steering linkage loose, ie outer tie rod or other front end wheel component that is loose or bad
Positive torque in mechanical systems causes rotation in one direction, while negative torque causes rotation in the opposite direction. Positive torque is typically associated with tightening or accelerating, while negative torque is associated with loosening or decelerating.
It seems as if your car is low on or out of motor oil. Having an oil change done should solve the problem.
The description that you provided gives me little clue about the circumstances when you experience this jerking. You did not mention a check engine light. The only thing I can think of is an engine misfire which should also set a check engine light. I have also owned Subarus that have quite a bit of driveline "slop". That is when going from decelerating to accelerating, or accelerating to decelerating, there is some looseness in various components that makes the transition less than smooth. This would be considered normal and is not a problem that you can fix without a lot of expense.
Force is directly related to the change in momentum of a body, as described by Newton's second law of motion. The force acting on an object causes a change in its momentum by accelerating or decelerating it. The greater the force applied, the greater the change in momentum experienced by the body.
In physics, a force is any influence that causes a free body to undergo a change in speed, a change in direction, or a change in shape.
A force causes an object to change its motion by accelerating or decelerating it. The direction and magnitude of the force determine how the object will move. If the force is unbalanced, the object will accelerate in the direction of the force.
Lack of propulsion.
