please create a video that explains each question presented---**Textual Information:** THEME: INTERACTIONS For example, the leaves of a tree move because a force is acting on it. The force comes from the wind. When the wind blows, it exerts a pushing force against the leaves and so it causes movement among the leaves. Forces can act on an object to bring about changes to its shape, speed or direction of movement A force has the following effects on objects: a. change the speed of a moving object - that is, slow down, stop or speed up the moving object. b. Cause a stationary object to start moving. c. Change the direction of motion of a moving object. For example, in a baseball game, the ball is moving towards the man and the man hits it with a bat. The ball then experiences a change in speed and direction. 4 Casco Publications Pte Ltd **Chart/Diagram Description:** **Diagram under a:** Type: Illustration showing forces acting on a moving ball. Main Elements: - Left panel: A ball on a surface. An arrow labeled "motion" points right above the ball. An arrow labeled "Force" points right, contacting the ball. Below, text says "Speed up". - Right panel: A ball on a surface. An arrow labeled "motion" points right above the ball. An arrow labeled "Force" points left, contacting the ball. Below, text says "Slow down or stop". **Diagram under b:** Type: Illustration showing a bowling ball hitting pins. Main Elements: - A bowling ball is shown on the left, positioned as if moving towards pins. - Three bowling pins are arranged in a triangle shape on the right, on a surface, ready to be hit. **Diagram under c:** Type: Illustration showing a baseball player hitting a ball. Main Elements: - A baseball player in batting pose, swinging a bat. - A baseball is shown near the bat, with radiating lines indicating impact. - An arrow indicates the initial direction of the ball towards the player (implied by context, not explicitly drawn). - A curved arrow shows the trajectory of the ball after being hit by the bat, indicating a change in direction. The ball is labeled.

Welcome to our lesson on forces and their effects. Forces are pushes or pulls that can change how objects move. Today we'll explore the first effect: how forces can change the speed of moving objects. When a force acts in the same direction as motion, it speeds up the object. When a force acts opposite to motion, it slows down or stops the object. The second effect of forces is causing stationary objects to start moving. When a force is applied to an object at rest, it can overcome the object's inertia and set it in motion. A perfect example is bowling, where the moving bowling ball applies force to the stationary pins, causing them to start moving and fall down. Forces are interactions that can change how objects behave. When forces act on objects, they can bring about changes to their shape, speed, or direction of movement. For example, when wind blows against tree leaves, it exerts a pushing force that causes the leaves to move and sway. The first major effect of forces is changing the speed of objects. When a force acts in the same direction as motion, it speeds up the object. When a force acts opposite to the direction of motion, it slows down or stops the object. Forces can also make stationary objects start moving. The third effect of forces is changing the direction of motion. When a force is applied at an angle to a moving object, it can redirect the object's path. In baseball, when the bat hits the ball, it applies a force that completely changes the ball's direction from moving toward the batter to flying away in a new direction. Forces are everywhere in our daily lives. When we push a door open, we apply force to change its position. Kicking a soccer ball demonstrates how force changes both speed and direction. Wind applies force to move clouds across the sky. Gravity constantly pulls objects downward. Understanding forces helps us explain how and why objects move in the world around us. To summarize what we have learned about forces: Forces are pushes or pulls that cause interactions between objects. They can change the speed of moving objects by speeding them up, slowing them down, or stopping them completely. Forces can also make stationary objects start moving and change the direction of motion. Understanding forces helps us explain the movements we observe in our daily lives.
