7Question

A force of 18 N acts on a 6 kg object. Calculate the acceleration.

8Question

A programmer stores force values in a list: [5, 8, 12, 3]. What is the total force if all forces act in the same direction?

9Question

Write pseudocode to find the net force from an array of force values acting in the same direction.

13Question

A force has components Fx = -9 N and Fy = 12 N. What is the magnitude?

14Question

Write a formula or code expression to compute the magnitude of a 2D force vector from fx and fy.

15Question

A class records forces in arrays fx = [2, -3, 4] and fy = [5, 1, -2]. What are the total x- and y-components of the net force?

16Question

Using the totals from Question 15, what is the magnitude of the net force?

17Question

Write pseudocode for a simulation that updates velocity using force, mass, and time step dt. Use the relationship a = F/m.

18Question

A simulation has mass = 2 kg, force = 10 N, dt = 0.5 s, and initial velocity = 4 m/s. What is the new velocity after one update?

19Question

Write a short Python-style expression that checks whether an object is accelerating, given net_force. Assume it accelerates when net_force is not 0.

20Question

A game character experiences three forces in one dimension: 15 N to the right, 6 N to the left, and 9 N to the right. Write the net force and state whether the character accelerates to the right or left.

Answer Key

#	Answer
1	A force is a push or pull that can change an object’s motion or shape.
2	The SI unit of force is the newton, symbol N.
3	An object stays at rest or keeps moving at constant velocity unless acted on by an unbalanced external force.
4	It continues moving at constant velocity, so its speed and direction do not change.
5	Fnet = m × a
6	F = ma = 4 × 3 = 12 N
7	a = F/m = 18/6 = 3 m/s²
8	28 N
9	Set total to 0; for each force in the array, add force to total; output total.
10	mass * acceleration
11	mass * acceleration
12	Magnitude = sqrt(6² + 8²) = sqrt(36 + 64) = sqrt(100) = 10 N
13	Magnitude = sqrt((-9)² + 12²) = sqrt(81 + 144) = sqrt(225) = 15 N
14	sqrt(fxfx + fyfy) or (fx2 + fy2) ** 0.5
15	Net Fx = 2 + (-3) + 4 = 3 N; Net Fy = 5 + 1 + (-2) = 4 N
16	Magnitude = sqrt(3² + 4²) = 5 N
17	Compute acceleration as force divided by mass; update velocity by adding acceleration times dt to the current velocity.
18	a = 10/2 = 5 m/s²; change in velocity = 5 × 0.5 = 2.5 m/s; new velocity = 4 + 2.5 = 6.5 m/s
19	net_force != 0
20	Net force = 15 - 6 + 9 = 18 N to the right; yes, it accelerates to the right.
