A7kg bowling ball is resting on the counter. how much force does the bowling ball have on the counter.

That "force" is what scientists and dieticians call the "weight" of the ball.

Weight = (mass) x (acceleration of gravity)

On or near the Earth's surface, the acceleration of gravity is 9.8 m/s² .

Weight of the ball = (7 kg) x (9.8 m/s²)

Weight of the ball = 68.6 kg-m/s²

The unit " kg-m/s² " is called "Newton".

Weight of the ball = 68.6 Newtons

(that's about 15.4 pounds)

= = = = = = = = = =

Note:  We don't usually talk about it, but the counter is also pushing   UP on the ball, with exactly the same amount of force.
