AP Physics with Hansenator - Quarter 1 Exam - Forces, Kinemaitcs, and More

Hello Every One! A test I gave to my Physics students this semester. I included a bonus that you may see soon on Energy! Solutions to this test will be posted tomorrow. Enjoy the fun and feel free to use it in your classroom!

Physics Kinematics and Forces Test

True/False (Make sure your answer is clear)

1. When summing Cartesian vectors the resultant vector is of the form <x_1+x_2,y_1+y_2>.
2. When a ball is thrown, at the top of the curve the acceleration in the y direction is 0.
3. There are 4 significant digits in the number .002016.
4. The magnitude of the polar (r,θ) vector <3,200°> is 3.
5. The magnitude of the Cartesian (x,y) vector <1,3> is √4.
6. When a ball is thrown, at the top of the curve the velocity in the y direction is 0.
7. A car moving at 11 m/s for 5 s travels a distance of 11/5 meters.
8. When a ball is thrown, the horizontal acceleration is 0.
9. x=rsin(θ) and y=rcos(θ).
10. Acceleration is defined as the change in velocity over the change in time.
11. In projectile motion, the vector for acceleration in the x and y directions is constant.
12. When considering projectile motion in the y-direction we use S=1/2 at^2+v_0y t+S_0
13. The angle that gives a projectile the farthest distance is 60°.
14. Neglecting air resistance, a bowling ball and a feather fall at the same rate.
15. If a ball rolls of a table at 5 m/s, the initial velocity in the y direction is 5 m/s.
16. The velocity at the top of a curve is zero in the x direction.
17. The velocity at the top of a curve is zero in the y direction.
18. An object in equilibrium has no forces acting on it.
19. An object in equilibrium never moves.
20. Newton’s Second Law states an object at rest stays at rest and an object in motion stays in motion unless acted on by an outside force.
21. The force of friction is found by multiplying the force of gravity by a frictional constant.
22. Kepler’s First Law states that planets move in a circular orbit.
23. Static friction determines if an object will begin to move.
24. The force of gravity between objects quadruples when the distance between them is cut in half.

Short Answer (Include units in you final answers and show all work.)

Number 1

Consider the two weights in the pulley system. Find the acceleration of the system.

Number 2

A golf ball is hit of a 25.0 m high building at an angle of 12 degrees with an initial velocity of 41.0 m/s. How far does it go horizontally before it hits the ground?

Number 3

If you throw a ball with an initial velocity of 3.25 m/s straight up in the air from a height of 10.0 m: (a) how long does it take the ball to reach the top of its motion? (b) How far will the ball rise before it begins to fall?

Number 4

Convert each of the following quantities:
(a) 400 cm to m
(b) 50 m to km
(c) 5 mg to g
(d) 5 m/s to ft/min

Number 5

Assume the 8.20-kg box moves. Find the acceleration if the kinetic friction is μ=.25.
