A force is a push or pull that can change an object’s motion.

2. What are the two main types of forces?

Contact forces (objects must touch), like friction or applied force Non‑contact forces (objects don’t touch), like gravity or magnetism

3. What is Newton’s First Law of Motion?

An object will stay at rest or keep moving at a constant speed unless a force acts on it. This is also called the law of inertia.

Inertia is an object’s resistance to changes in motion. Heavier objects have more inertia.

5. What is Newton’s Second Law of Motion?

Force equals mass times acceleration. This means the more force you apply, the more an object accelerates.

6. What is Newton’s Third Law of Motion?

For every action, there is an equal and opposite reaction.

Speed is how fast something moves

Velocity is speed in a specific direction.

9. What is acceleration?

Acceleration is a change in speed or direction.

10. What is friction?

Friction is a force that opposes motion when two surfaces rub against each other.

11. Why do objects slow down when sliding across the floor?

Because friction acts in the opposite direction of motion.

12. What happens when unbalanced forces act on an object?

Its motion changes. It may speed up, slow down, or change direction.

Gravity is a non‑contact force that pulls objects toward each other, especially toward Earth

14. Why does a heavier object have more inertia than a lighter one?

Because it has more mass, making it harder to start or stop its motion.
