- 2.
An object in motion will _____________________ if the Net force acting on it is____
-
Stay in motion, 0 N
-
Accelerate, 0 N
-
Stay in motion,greater than 0 N
Correct Answer
A. Stay in motion, 0 NExplanation
Newton's first law is defined as an object in motion will stay in motion if the net fore acting on it is 0NRate this question:
-
- 3.
If an object is in equilibrium its acceleration is _________ and its Net force is _____
-
Non-zero, non-zero
-
Zero,non-zero
-
Zero, zero
-
Non-zero,zero
Correct Answer
A. Zero, zeroExplanation
If the net force = 0 N, then the objects acceleration = 0 N. No net force = no accelerationRate this question:

- 4.
Johnny pushes with a force of 50 N to the left, Jill pushes on the car with a force of 75 N to the right. What is the net force acting on the object?
-
125 N
-
100 N
-
50 N
-
25 N
-
0 N
Correct Answer
A. 25 NExplanation
When fores are going in opposite directions, you subtract ( or add a negative)- FNET= 75N - 50 NRate this question:

- 5.
Johnny pushes with a force of 50 N to the left, Jill pushes on the car with a force of 75 N to the right. Is the object in equilibrium?
-
Yes
-
No
-
Maybe
Correct Answer
A. NoExplanation
If the net force is not zero, The object is not in equilibriumRate this question:
-
- 6.
An object is moving at a constant velocity. If the Car requires 1000 N of force to propel it forward, What is the magnitue of the frictional force acting on the car?
-
0 N
-
500 N
-
1000 N
-
1500N
-
1000 N
Correct Answer
A. 1000 NExplanation
Since it is moving at a constant spee, the Net force on it )n, Which means it must be balanced by a force that is equal and opposite to the applied forceRate this question:
-
- 7.
An object is moving at a constant velocity. If the Car requires 1000 N of force to propel it forward, Is the car in equilibrium?
-
Yes
-
No
-
Maybe
Correct Answer
A. YesExplanation
yes, Equilibrium describes constant motion. An object moving at a constant or uniform velocity is in equilibriumRate this question:
-
- 8.
What is the approximate weight of a 10 kg dog?
-
1 N
-
10 N
-
100N
-
1000 N
Correct Answer
A. 100NExplanation
w=mg, w= 10kg *9.8m/s^2= 980N= 1000NRate this question:
