What is an Balanced Force?
Provide a example in the classroom?
When forces are balanced they cancel each other out, resulting in no change in motion.
500
A cheetah runs 1,500 meters in 2.5 minutes.
What is its speed in meters per second?
10 meters per second
(2.5 minutes = 150 seconds → 1,500 ÷ 150 = 10 m/s)
500
A force moves a 4 kg object from rest to a speed of 16 m/s in 4 minutes. What is the net force?
What is 0.27 N?
→ 4 minutes = 240 seconds
→ Acceleration = (16 m/s - 0 m/s) ÷ 240 s = 0.0667 m/s²
→ F = ma → 4 kg × 0.0667 ≈ 0.27 N
500
An object accelerates at 2 m/s² when a force of 30 N is applied.
What is the mass of the object?
15 kilograms
