This time place the jar over the ball on a hard surface. If you can’t pick up the ball, start again.You notice that it is difficult to do so, but you may be able to figure out the experiment with a little trial an error. First attempt the pick up the ball using the jar.Bouncy balls are great for this experiment, as are pint sized canning jars. Gather a small ball and a jar with a mouth that is bigger than the ball.In the case of Newton’s First Law, gravity is the force acting on the ball that will stop its motion. If you stop (or slow down) the circular motion of the jar, the force of gravity will become greater than the centripetal force and the ball will fall out of the jar. As long as you continue to spin the jar at a constant rate, the ball will continue to spin at the same rate allowing you to pick up the ball with the jar. Newton’s First Law of Motion states that an object at rest will stay at rest, and an object in motion will stay in motion unless acted on by an outside force. This centripetal force allows you to pick up the ball with the jar. This creates a centripetal force which is greater than the force of gravity pulling down on the ball.Ĭentripetal force is any force that causes an object to move in a circular path. With the ball and jar both moving in the same direction, the jar pushes against the ball and the ball pushes against the jar. This is because the ball is accelerating due to its constant change in direction. When you spin the jar in a circle, the ball will begin to move in a circle along with the jar. How to Pick Up a Ball with a Jar Science Experiment Step by Step Video How Does the Science Experiment Work Instead, keep practicing and you will eventually be able to pick up the ball. Don’t get discouraged if you can’t do it the first time. Helpful Tip: While this experiment looks easy to perform, it does take practice to get it down. Do you know the reason why you were able to pick up the ball with the jar? Find out the answer in the how does this experiment work section below. Now, take a moment to write down your observations. You have just successfully picked up the bar, using just the jar. Step 4 – Continue moving the jar in a circular motion and lift it off the table. Helpful Tip: This step will take practice and patience, but if you take your time you will eventually get the ball to move up into the glass. ![]() As this happens, begin moving the jar faster and faster until the ball moves up into the jar. The ball will eventually begin moving along the rim of the jar. Step 3 – Next, begin to move the jar in circular motions around the ball. If you can’t pick up the ball, start again. You notice that it is difficult to do so, but you may be able to figure out the experiment with a little trial and error. Step 2 – Next, attempt the pick up the ball using the jar. Helpful Tip: Bouncy balls are great for this experiment, as are pint-sized canning jars. Without using your hands to touch the ball, do you think it is possible to pick up the ball with the jar? Set a ball on the table and ask some questions. Step 1 – Gather a small ball and a jar with a mouth that is bigger than the ball. Pick Up a Ball with a Jar Science Experiment Instructions ![]()
