Question13. Which of the following would occur as a result of fribalanced orces? A. A satellite orbits Earth at a constant speed. B. Twelve children learn their shoulders against a single wall. C. A bus moves along a highway in a straight line at 65 miles per hour. D. Two tug-of-war teams move an inch in one direction and then an inch in the opposite direction.
Studdy Solution
STEP 1
1. The problem involves understanding the concept of balanced forces.
2. Balanced forces imply that the net force acting on an object is zero.
3. We need to identify which scenario represents balanced forces.
STEP 2
1. Define balanced forces.
2. Analyze each scenario to determine if balanced forces are present.
3. Identify the scenario that correctly represents balanced forces.
STEP 3
Balanced forces occur when the sum of all forces acting on an object is zero, resulting in no change in the object's motion.
STEP 4
Analyze scenario A: A satellite orbits Earth at a constant speed. - Even though the speed is constant, the direction changes, indicating a centripetal force is acting, which means forces are not balanced.
STEP 5
Analyze scenario B: Twelve children lean their shoulders against a single wall. - The wall does not move, suggesting that the forces exerted by the children are balanced by the wall's resistance.
STEP 6
Analyze scenario C: A bus moves along a highway in a straight line at 65 miles per hour. - The bus is moving at a constant speed in a straight line, indicating balanced forces (net force is zero).
STEP 7
Analyze scenario D: Two tug-of-war teams move an inch in one direction and then an inch in the opposite direction. - The movement back and forth suggests unbalanced forces as the teams are not in equilibrium.
STEP 8
Identify the scenario that represents balanced forces:
- Scenario B: Twelve children leaning against a wall, as the wall does not move, indicating balanced forces.
- Scenario C: A bus moving at a constant speed in a straight line, indicating balanced forces.
The scenarios that represent balanced forces are:
