FleurDaisy's YouTube suggestion is a good one. There are lots of examples of take-offs and landings.
The plane starts off attached to the bit where everyone gets on (the 'gate') then is pushed back* by ground staff and the pilot and team will drive it to the start of the runway (there may be a couple of aircraft in front) so there can be a bit of a stop and start as it lines up in the queue. Once the plane is cleared for take off the engines will pick up speed and you'll move forward much more quickly to take off.
I love this bit!
The actual take off itself is often imperceptible and you'll see the angle change out the window.

Here's an edited-but-mostly-real-time video of someone's journey from Lanzarote to London Gatwick earlier this year, on an Airbus A320 - push back starts at about 3m 10sec, engines start a minute later, plane starts moving under its own power around 7min as it taxis towards the runway. The plane arrives at the runway by 9min 50s and briefly comes to a stop (sometimes there can be a delay before actual take off, but not here) and the engines increase speed at 10min with the plane whizzing forward for about 25 seconds before lifting off and heading upwards until you get to about 37,000 feet.
The landing bit starts at 22:43 (the aeroplane is now lined up with the runway but still a few hundred feet up), gradually descending until it lands at 23:51 then decelerates down the runway before heading to the airport gate to let everyone off.
Have a great holiday :)

*there's a vehicle with an attachment that literally pushes the aircraft away from the gate
