Newtons second law lab

acceleration of a cart lab report answers

Measure the distance that the tennis ball moves on the floor. Drop the ball of paper from the same height into a bowl with the same amount of the same powder. Take a toy car and place it at the top of the ramp and release it.

Release the ball so that it swings down and hits the other tennis ball.

cart and hanging mass lab report answers

Add three gram masses to the cart. Throughout this experiment the hanging mass force is increased which reduces the amount of air resistance it faces, thus making the acceleration faster, but still constant with the other accelerations.

The relationship between the acceleration and mass is proportional.

Mark the distance that the toy car has moved on the floor. That instant of time is shown in the "Time s " column next to its associated velocity.

At some instant during that time interval the cart's instantaneous speed equals the average speed for the interval. Repeat the experiment, substituting a plastic Wiffle ball for the softball on the floor, and measure how far it rolls after impact. Take a toy car and place it at the top of the ramp and release it. Add three gram masses to the cart. Make sure the cart's flag is before the first gate when the hanger is all the way up near the pulley as shown in Fig. References University of Virginia Physics Department: Newton's Second Law of Motion Experiments About the Author Wilhelm Schnotz has worked as a freelance writer since , covering arts and entertainment, culture and financial stories for a variety of consumer publications. You will notice that as more coins are added, the farther the car moves.

Move the hanging softball and place another softball on the marked spot. Place a toy car at the top of the ramp. Now place a bowl filled with powdered sugar or flour underneath the rock, and drop it from a fixed height into the powder.

Applying newtons second law

Even though the change in air resistance might be minor, it is still another source of error that can lead to miscalculation. Also, make sure the cart's flag passes the second photogate before the hanger hits the ground. Repeat the experiment with five washers taped to the top of the car. Another force that we excluded was air resistance. This will ensure that the cart is being accelerated in the region between the two photogates. Begin with an empty wagon. Hot Wheels Experiment Construct a simple ramp 18 inches high and about 24 inches long using a piece of thin plywood and bricks. Take a toy car and place it at the top of the ramp and release it. When ready to record data, click the Start button. Tennis Ball Activity Things that you will need: two tennis balls, a cricket ball, a rubber ball, a plastic ball, some string and a metre scale Hang a tennis ball using string from the centre of the lintel of a door frame so that the tennis ball hangs just two or three centimetres above the floor. Release the cart and catch it when it reaches the end of the track.

Pull the hanging softball back so it is three feet from the ground and release it so it swings and hits the softball on the floor.

Place the car on the top of the ramp and release it.

Newtons second law examples

Because acceleration was constant, the difference in size between the crater made by the rock and the one made by the paper illustrates that an increase in mass directly increases the force of the impact into the flour. That instant of time is shown in the "Time s " column next to its associated velocity. Tennis Ball Activity Things that you will need: two tennis balls, a cricket ball, a rubber ball, a plastic ball, some string and a metre scale Hang a tennis ball using string from the centre of the lintel of a door frame so that the tennis ball hangs just two or three centimetres above the floor. You will notice that the toy car rolls down the ramp and also moves some distance before it stops. Throughout this experiment the hanging mass force is increased which reduces the amount of air resistance it faces, thus making the acceleration faster, but still constant with the other accelerations. Make sure the cart's flag is before the first gate when the hanger is all the way up near the pulley as shown in Fig. Tie the string around the wagon handle and leave 2 or 3 feet of string hanging off the handle to pull with. Figure 7: Sample data table 12 The cart's speed increases smoothly during the time interval while the flag passes through the photogate beam. You will notice that as more coins are added, the farther the car moves. Figure 3: Photogate set-up Figure 4: Experimental set-up 4 Connect photogate 1 to digital channel 1 and photogate 2 to digital channel 2. Take a toy car and place it at the top of the ramp and release it.

Softball Experiment Screw an eyelet into a softball and another into the lintel of a door frame.
