What is the formula for Newton's second law of motion?
-
F=ma
-
F=mph
-
F=d/t
-
F=ml
Correct Answer
A. F=maExplanation
Newton's second law of motion states that the force acting on an object is equal to the mass of the object multiplied by its acceleration. This formula, F=ma, represents the relationship between force, mass, and acceleration. It shows that the force experienced by an object is directly proportional to its mass and the rate at which its velocity changes. By using this formula, one can calculate the force required to accelerate an object of a given mass.Rate this question:

How much force is needed to accelerate a 200 kg motorcycle at 4 m/s2?
-
600 N
-
800 N
-
10000 N
-
12000 N
Correct Answer
A. 800 NExplanation
To calculate the force needed to accelerate an object, we can use the formula F = m * a, where F is the force, m is the mass, and a is the acceleration. In this case, the mass of the motorcycle is given as 200 kg, and the acceleration is given as 4 m/s^2. Plugging these values into the formula, we get F = 200 kg * 4 m/s^2 = 800 N. Therefore, the correct answer is 800 N.Rate this question:

If a 70 kg skydiver jumped out of a plane, what would be the force of his falling?
-
545 N
-
7.14 N
-
0.14 N
-
686 N
Correct Answer
A. 686 NExplanation
The force of the skydiver's falling would be 686 N. This is because the force of gravity acting on an object is equal to its mass multiplied by the acceleration due to gravity. In this case, the skydiver's mass is 70 kg, and the acceleration due to gravity is approximately 9.8 m/s^2. Therefore, the force of the skydiver's falling would be 70 kg * 9.8 m/s^2 = 686 N.Rate this question:

Gravity near Earth’s surface causes falling objects to accelerate at a rate of 9.8 m/s2.
-
True
-
False
Correct Answer
A. TrueExplanation
The statement is true because gravity on Earth does indeed cause falling objects to accelerate at a rate of 9.8 m/s^2. This acceleration is commonly referred to as the acceleration due to gravity and is the same for all objects regardless of their mass. It means that for every second an object falls, its velocity increases by 9.8 meters per second. This constant acceleration is a fundamental concept in physics and is an important factor in understanding the motion of objects in free fall.Rate this question:

Terminal Velocity is the point at which a free-falling object cannot accelerate any more due to what two are forces working against each other?
-
Gravity and Air Resistance
-
Gravity and Mass
-
Air Resistance and Mass
-
Gravity and Newton's
Correct Answer
A. Gravity and Air ResistanceExplanation
Terminal velocity is the maximum velocity that a free-falling object can reach when the forces of gravity and air resistance are balanced. Gravity is the force that pulls the object downward, while air resistance is the force that opposes the motion of the object through the air. As the object falls, the force of gravity increases, causing the object to accelerate. However, as the object accelerates, the force of air resistance also increases. Eventually, the force of air resistance becomes equal to the force of gravity, resulting in a net force of zero and causing the object to reach its maximum velocity, known as terminal velocity.Rate this question:

Newton's second law of motion means that a basketball would require more force to accelerate than a bowling ball.
-
True
-
False
Correct Answer
A. FalseExplanation
Newton's second law of motion states that the force required to accelerate an object is directly proportional to the mass of the object. Therefore, a basketball and a bowling ball would require the same amount of force to accelerate if their masses are the same. Since the question does not specify the masses of the basketball and the bowling ball, we cannot conclude that a basketball would require more force to accelerate than a bowling ball. Hence, the correct answer is False.Rate this question:

If 20 N of force were applied to a 16 kg bowling ball, at what rate would it accelerate?
-
1.25 m/s2
-
0.8 m/s2
-
320 m/s2
-
45 m/s2
Correct Answer
A. 1.25 m/s2Explanation
F = ma. If you know F (20 N) and you know mass (16 kg), then you must solve for a. So, a=F/m or a=20/16, which is 1.25 m/s2.Rate this question:

If a ping pong ball falls off a table and hits the ground with 4 N of force applied to it, what is its mass?
-
2.45 kg
-
0.41 kg
-
39.2 kg
-
4.3 kg
Correct Answer
A. 0.41 kgExplanation
Since the ball is falling from the table we know the acceleration of gravity is 9.8 m/s2. So, we are solving for m. That means m=F/a or m=4/9.8 = 0.41 kg.Rate this question:

Increasing the mass but keeping the force constant causes the acceleration to decrease.
-
True
-
False
Correct Answer
A. TrueExplanation
When the mass is increased while keeping the force constant, according to Newton's second law of motion (F=ma), the acceleration will decrease. This is because the force needed to move a larger mass is greater, and since the force remains constant, the resulting acceleration will be smaller.Rate this question:
