You're Correct!

Accelerating the club head at the bottom of your golf swing results in you achieving maximum club head speed, as you strike the golf ball. With the club head hitting the golf ball when it is travelling at its fastest, you will achieve maximum shot distance when you play your golf shots.

The bottom of your golf swing is the lowest point of your swing arc. If you imagine, in basic terms, that the golf club head travels around you on a semi-circle as you swing back away from the golf ball and then it swings back down that semi-circle to the golf ball and finishes by travelling around another semi-circle as you follow through. The bottom of your swing is the bottom of this circle, or arc, that the club head creates around you.

You want to achieve your impact position at the bottom of this swing arc as the club head will strike the golf ball solidly if it makes contact in this position. Accelerating at the bottom of your golf swing when the club head connects with the golf ball, results in you achieving maximum club head speed as the ball is hit and this means that you will achieve maximum shot distance and length. The further that you can hit the golf ball, the easier you are making the game because you are getting the ball closer to the hole in less shots.

If the club head accelerates before it gets to the bottom of your golf swing, then it is reaching maximum club head speed before it strikes the golf ball. This speed is wasted as it peaks before there is a connection between the club head and the golf ball and therefore the club head actually strikes the ball as it is decelerating and slowing down, so maximum shot length is not achieved.

If the club head peaks with its maximum speed after the bottom of your swing arc, then the club head will have already struck the golf ball before it has reached its maximum speed. This will result in less shot distance being created than if the maximum club head speed is achieved at the bottom of your swing, when you connect the club head with the golf ball.

If you accelerate and reach peak club head speed as you begin your down swing, then you are wasting your acceleration as the club head does not strike the golf ball early in the down swing. Time your acceleration to peak at the bottom of your swing where the club head impacts with the golf ball to achieve maximum shot length.

If you do not accelerate in your golf swing, you will not achieve the shot length that you could if you did accelerate. On average, more consistent golfers swing down three times faster than they make their back swing, so they accelerate and generate more speed in the movement of the club head as they swing through impact.

If you accelerate after you have struck the golf ball, you have wasted the speed that you have created by mis-timing the connection that you make between the club head and the golf ball and when the full club head speed is delivered.
