1120 - How does an object's speed and change in speed relate to time and distance

Let's break it down in simple terms:

1. Speed: Speed is how fast an object moves. It's like how quickly you can run or ride your bike.

2. Change in Speed: This is also known as acceleration. It's how fast your speed is changing. Imagine you're on a bike - if you press the pedals faster, your speed increases, and if you use the brakes, your speed decreases.

Now, let's connect speed and change in speed to time and distance:

• Time: If you travel at a certain speed for a certain amount of time, you'll cover a certain distance. Think of it like this: if you ride a bike at 10 miles per hour for 2 hours, you'll cover a distance of 20 miles.

• Distance: This is how far you've traveled. So, if you have a certain speed and you travel for a certain amount of time, you'll cover a certain distance. For example, if you run at 5 miles per hour for 3 hours, you'll cover a distance of 15 miles.

Here's a simple formula to remember: Distance = Speed x Time.
