Answers
1
What quantity is defined as the force of gravity?
Mass
Normal Force
Weight
Frictional Force
2
Which of the following relationships is correct?
1 N = 1 kg·m/s
1 N = 1 kg
1 N = 1 kg·m
1 N = 1 kg·m/s2
3
The property of matter that resists changes in motion is called:
friction
weight
inertia
gravity
4
What is the difference between mass and weight?
Mass is in Newtons, weight is in kilograms
Weight is mass times g
They are the same
Mass can change, weight can not change
5
An astronaut travels far away from Earth, her weight...
decreases because her mass decreases.
increases because gravity increases.
decreases because gravity decreases
remains the same because her mass remains the same.
6
Which diagram represents a person moving downwards and speeding up?
C
A
Both A and B
B
7
What is the correct common unit for weight?
kilograms
Newtons
pounds (lbs)
m/s2
8
A block slides down a frictionless incline, which of the following statements is true?
Its speed increases and its acceleration decreases
Its speed and acceleration remain constant
Both its speed and acceleration increase
Its speed increases and its acceleration remains constant
9
What is the support force exerted by a surface (when the object is resting on said surface)?
Normal Force
Frictional Force
Weight
Natural Force
10
If a force of 12 N is applied to an object with a mass of 2kg, the object will accelerate at?
6 m/s2
12 m/s2
24 m/s2
0.17 m/s2
11
An astronaut travels to the moon. How does her mass on the Earth compare to her mass on the moon?
her mass is less on the moon
her mass is the same on the moon.
her mass is more on the moon
12
There is a mistake in this free-body diagram. What is it? Disregard frictional forces.
The weight of the hanging mass should be smaller thantension
The weight of the hanging mass should be larger than tension
There is nothing wrong with this free-body diagram
m1g should be bigger than the normal force
13
A truck loaded with sand accelerates (force remains constant). As sand leaks, acceleration
remains the same
increases at a steady rate
increases then decreases
decreases at a steady rate
14
When a car (your system) moves forward, what is the thing pushing it forward?
The Earth's gravitational pull
The road
The gas
The motor
15
What is another name for F = ma?
Newton's 3rd Law
Newton's 2nd Law
Newton's 1st Law
It's just another equation
16
Which free-body diagram for the block is correct?
A
D
C
B
