A person throws a marble straight up into the air, releasing it a short height above the ground and catching it at that same height. If air resistance is negligible, which of the following graphs of position y versus time t is correct for the motion of the marble as it goes up and then comes down?
Area under the curve of a Force v Time graph
Impulse
Work
Spring Constant
An object is coming to rest. Does increasing the stop time lower the amount of force experienced?
Yes, Δp = F⋅t so higher time must equal lower force for same impulse
No, airbags work by causing a counter force on the body. This lowers the Net force experienced by adding a force in the negative direction.
A ball is thrown up into the air, which graph best matches its velocity versus time.
The picture is an example of Newton's...
1st Law

The system shown above is released from rest. If friction is negligible, the acceleration of the 4.0 kg block sliding on the table shown above is most nearly (a) .
The student wishes to determine the spring constant of the spring using the measurements of the period of oscillation. Which of the following pieces of equipment would provide another measured quantity that is sufficient information to complete the determination of the spring constant?
Meter stick
Motion sensor
Balance
Photogate
Shown in a top view are six uniform rods that vary in mass M and Length L. Also shown are circles representing vertical axis around which the rods are going to be rotated in a horizontal plane and arrows representing forces acting to rotate the rods. The forces change direction in order to always act perpendicular to the rods. Rank these rods, from greatest to least, on the magnitude of the their angular acceleration. The moment of inertia formula for rod about end I = (1/3)ML^2.

Which of the following statements is true about the image above?
The accelerations of the blocks will vary according to their mass
The net force acting on each block is the same
The blocks will experience the same acceleration
The 3m box will eat the 2m and the m boxes
Which of the following is constant for an object in uniform circular motion?
Velocity
Acceleration
Displacement
Kinetic Energy
Two blocks of masses 1.0 kg and 2.0 kg, respectively, are pushed by a constant applied force F across a horizontal frictionless table with constant acceleration such that the blocks remain in contact with each other, as shown above. The 1.0 kg block pushes the 2.0 kg block with a force of 2.0 N. The acceleration of the two blocks is (a) .
A 2-kg object is a distance of 10,000,000 meters away from the center of Earth, which has a mass of nearly 6 × 1024 kg. What is the approximate gravitational field strength of Earth’s gravitational field at the location of the 10-kg object?
2 N/kg
4 N/kg
10 N/kg
The gravitational field strength is negligible and, therefore, approximately zero.
In which of the following situations is the kinetic energy of the object decreasing?
A sphere is dropped from a building.
A satellite is moving in a circular orbit around the earth.
A baseball is heading upward after thrown at an angle.
An elevator is moving upward at a constant velocity.
Based on your findings, which equation could best describe the pendulum’s period?
A
B
C
D
Which graph shows an object getting faster?
