Which of the following best describes Newton's First Law of Motion?
An object in motion will eventually stop unless acted upon by an external force.
An object at rest will remain at rest, and an object in motion will remain in motion unless acted upon by an external unbalanced force.
For every action, there is an equal and opposite reaction.
The acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass.
According to Newton's Second Law of Motion, what is the formula for force?
F=ma
F=am
F=m+a
F=ma
Which of the following scenarios best illustrates Newton's Third Law of Motion?
A person pushing a wall and the wall pushing back with equal force.
A car accelerating on a highway.
A ball falling to the ground due to gravity.
A satellite orbiting the Earth.
If a 10 kg object is subjected to a net force of 50 N, what is its acceleration?
2m/s2
5m/s2
10m/s2
50m/s2
Which of the following statements is true about mass and weight?
Mass and weight are the same and can be used interchangeably.
Mass is a measure of the amount of matter in an object, while weight is the force exerted by gravity on that object.
Weight is a measure of the amount of matter in an object, while mass is the force exerted by gravity on that object.
Both mass and weight change depending on the location of the object.
A 5 kg object is moving with an acceleration of 3m/s2 . What is the net force acting on the object?
0.6N
8N
15N
25N
Which of the following is an application of Newton's First Law of Motion?
A spacecraft continuing to move in space without using its engines.
A ball falling to the ground due to gravity.
A person pushing a wall and the wall pushing back with equal force.
What happens to the acceleration of an object if the net force acting on it is doubled, assuming the mass remains constant?
The acceleration is halved.
The acceleration remains the same.
The acceleration is doubled.
The acceleration is quadrupled.
Which of the following best describes the relationship between force, mass, and acceleration?
If the mass of an object doubles, it would require twice the force to make it accelerate the same amount.
If the mass of an object doubles, it would only take half of the force to make it accelerate the same amount.
If a 20 kg object is subjected to a net force of 100 N, what is its acceleration?
2m/s2
4m/s2
5m/s2
10m/s2
Which of the following is an example of Newton's Third Law of Motion in action?
A book remaining on a table until someone moves it.
A car accelerating when the gas pedal is pressed.
A rocket launching into space by expelling gas downwards.
A ball rolling down a hill.
What is the weight of a 10 kg object on Earth, where the acceleration due to gravity is 9.8m/s2 ?
9.8N
98N
980N
0.98N
Which of the following best describes the concept of inertia?
The tendency of an object to accelerate when a force is applied.
The tendency of an object to resist changes in its state of motion.
The force exerted by gravity on an object.
The acceleration of an object due to a net force.
If a 15 kg object is moving with an acceleration of 2m/s2 , what is the net force acting on the object?
10N
20N
30N
40N
If all 4 forces of flight are balanced on a plane, which of the following must be true?
The plane is accelerating
The plane is not moving
The plane is moving at constant speed
If the weight of a plane is greater than its lift force, what must be true?
The plane is taking off
There is no acceleration
The plane is descending
The girl on the sled will remain in motion unless
her motion is changed by magnetic forces.
