# Parallel forces physics lab

Find and entry where the measured force is similar on both tables. This will fit a straight line to your data.

Attach a Force Sensor to the bracket. Students will be able to modify the mass of the object, the spring constant of the spring and the amount of compression for the spring.

See Answer Graph D is the correct answer. Olive claims that the normal force is N; Glen claims that the normal force is N; and Warren claims that the normal force is N. Record the force on the force sensor. Discuss with your partner why calibration is necessary. The hanging mass should be just below the smart pulley.

Curling Momentum Lab This lab is designed to have students investigate the nature of a nonlinear collision using curling stones. Call over a TA or instructor and explain your conclusion to them. It is the parallel component of the weight vector that causes the acceleration.

Since the tension is constant in the string, the object with mass M and the hanging mass m have the same acceleration.

Component method - Resolve the vector into components by choosing two perpendicular axes, X and Y, and projecting each vector onto these axes.

The ball rolls northward up the driveway and then rolls back to Johnny. It is in the laboratory that physics students learn to practice the activities of scientists - asking questions, performing procedures, collecting data, analyzing data, answering questions, and thinking of new questions to explore.

Attach the force sensor to the cart with the adapter. Click and drag the cursor to select the same data on the force vs. Position the cart at the far end of the track. What is the acceleration of the cart in terms of m, M and g.

Make a plot of Tcalculated mweight g-a vs. The Fgrav can be calculated from the mass of the object. Do not exceed g. Discuss with your partner why it is important to be sure the strings center washer is centered on the force table.

Observe your two tables:. The experiment shows that, when a number of parallel forces are in equilibrium: (i) the sum of the forces in one direction is equal to the sum of the forces in the opposite direction; (ii) the sum of the anticlockwise moments about any point is equal to the sum of the clockwise moments about the point.

The lab ideas and associated pages in The Laboratory section of this web site are designed to help teachers improve their lab programs by adopting labs with a purpose. There are over lab ideas presented here - but their presentation is much different than the traditional presentation of a lab.

Parallel force systems are those in which forces act in the same direction. The opposite of a parallel force system is a perpendicular force system, which is a system that has forces acting at right angles to each other. Compare the attitudes to war in the three poems ‘Rule Britannia’ was written in The title ‘Rule’ causes the reader.

If the string connected to the cart does not run parallel to the table, move the smart pulley up or down until the string is parallel. Tie a small loop at the end of the hanging string. Hang a 50 g mass from the loop.

A cart resting on a horizontal surface accelerates because of the tension in the string it's connected to. From the free body diagram shown in Figure 3, we see that the total force on the mass is the force of gravity minus the string’s tension.
