Question

7 what could be true about an object with no net forces acting on it? choose three. the applied force is greater than the frictional force the object remains at rest the forces acting on the object are balanced the object is moving at a constant velocity the object is accelerating

Explanation:

1. Analyze "The applied force is greater than the frictional force": If applied force > frictional force, there is a net force (net force = applied - frictional), so this is false.
2. Analyze "The object remains at rest": By Newton's first law, if net force is zero and the object is at rest initially, it stays at rest. This is true.
3. Analyze "The forces acting on the object are balanced": Net force is zero when forces are balanced (vector sum of forces is zero). This is true.
4. Analyze "The object is moving at a constant velocity": By Newton's first law, if net force is zero and the object is moving, it moves at constant velocity (constant speed and direction). This is true.
5. Analyze "The object is accelerating": Acceleration is caused by net force ($F = ma$). If net force is zero, acceleration is zero. So this is false.

Answer:

• The object remains at rest
• The forces acting on the object are balanced
• The object is moving at a constant velocity
