5. Identify one way we use friction in everyday life
6. Which of the following is a type of force?
Gravity is a force that pulls objects towards each other.
7. What is the unit of force?
Newton is the unit of force in the International System of Units (SI).
8. Which of the following is NOT a contact force?
Gravity is a non-contact force that acts over a distance.
9. When two forces are acting on an object in opposite directions, what is the result?
The object will accelerate in the direction of the stronger force.
10. Which of the following is an example of a balanced force?
A book at rest on a table experiences balanced forces.
11. What is the formula for calculating force?
Force is equal to the mass of an object multiplied by its acceleration.
12. What is the force that opposes motion between two surfaces in contact?
Friction is the force that opposes motion between two surfaces in contact.
13. Which of the following is a force that acts on an object in free fall?
Air resistance is a force that acts on an object in free fall due to the air it displaces.
14. What do you call the force that pulls objects towards the center of the Earth?
Gravity is the force that pulls objects towards the center of the Earth.
15. Which of the following is a force that keeps objects in circular motion?
Centripetal force is the force that keeps objects in circular motion by pulling them towards the center.
16. Which of the following is an example of a force of tension?
Tension is the force that occurs when a string or rope is pulled tight.
17. Which of the following is NOT a factor affecting the force of friction?
Temperature does not directly affect the force of friction between two surfaces.
18. What is the force that pushes or pulls objects that are electrically charged?
Magnetic force pushes or pulls objects that are electrically charged.
19. Which of the following is a force that needs contact to act?
Friction is a force that requires objects to be in contact for it to act.
20. When two forces are equal in size but opposite in direction, what is the result?
When two forces are balanced, the object remains stationary or moves at a constant velocity.
21. What force keeps the planets in orbit around the sun?
Gravity is the force that keeps the planets in orbit around the sun.
22. What is force?
Force is defined as a push or pull on an object.
23. Which of the following is an example of a contact force?
Frictional force is a contact force that occurs when two surfaces rub against each other.
24. What is the SI unit of force?
The SI unit of force is the Newton, named after Sir Isaac Newton.
25. Which of the following is an example of a non-contact force?
Air resistance force is a non-contact force that acts on objects moving through air.
26. What is the formula for calculating force?
The formula for calculating force is F = ma, where F is force, m is mass, and a is acceleration.
27. Which of the following is an example of a balanced force?
A balanced force is when two forces of equal strength act on an object in opposite directions.
28. What type of force keeps the planets in orbit around the sun?
Gravitational force is responsible for keeping planets in orbit around the sun due to the massive attraction between them.
29. Which of the following is an example of a force of friction?
The force of friction is the resistance created when two surfaces move against each other.
30. What happens to an object when an unbalanced force is applied to it?
An unbalanced force causes an object to accelerate in the direction of the force.
31. Which force opposes the motion of an object through a fluid?
Drag force opposes the motion of an object through a fluid like air or water, slowing it down.
