Unit 5 Test: Force and Motion1.A teacher points to a microscope sitting on the desk. Which conclusion bestexplains why the microscope is not moving?A.There are many forces acting on the microscope, but mostly it is its inertiathat keeps it on the desk.B. Gravity is pulling on the microscope. It is only the weight of the scope thatkeeps it from moving off the desk.C. There is only one force, air pressure, acting on the microscope. The air inthe room is pressing on the scope keeping it on the desk.D. There are two forces acting on the microscope. The desk is pushing up andgravity is pulling down. The balance of these forces keeps the microscopefrom moving.2.When an object is acted on by unbalanced forces, the object will ALWAYS—F.G.H.J.3.acceleratecontinue in the same directioncontinue at the same speedcome to a stopA car traveled 500 m at 30 km/hr, then traveled 200 m at 40 km/hr.

Unit 5 Test: Force and Motion7.Martin gathered a toy car, a ramp, a stopwatch, a meter stick, and a varietyof weights. What is he likely testing?A.B.C.D.8.howhowhowhowthe angle of a ramp affects the speed of the carmass affects the speed of the carfriction affects the speed of the carequal forces work on the placement of the car and the rampA 1000 kg rocket is moving forward at 10m/s in space. A 10,000 N force isapplied to the rocket for one second from behind.How fast is the rocket now traveling?F.G.H.J.9.20 m/s15 m/s10 m/s0 m/sA 2000 kg truck and a 500 kg car are racing. The same amount of forceis applied to each of them. What will happen?A.B.C.D.TheTheTheThetruck will accelerate twice as fast.car will accelerate four times as fast.car will accelerate twice as fast.truck will accelerate four times as fast.10. One of the laws of motion states, "Things in motion stay in motion unlessan unbalanced force acts upon it." On Earth, objects always seem to stop whenmore force is not being applied. What is causing the objects to stop?F.G.H.J.the normal forcefrictionweightgravity

Some Types of Testing User Acceptance Test: Test according to specification or requirement. Functional Test: Test one function (or feature) expected output. Unit Test: Test the smallest "unit" of testable code (in isolation). Integration Test: Test the interaction of "units" in 1 or more systems. Behavioral Test: Automated UAT or black box testing.
