In the seventh experiment, we measure the acceleration of the weight when it does not fall against the base All 1D acceleration sensor. Let's see what the force sensor does - if it's horizontal, it shows zero, if it's vertical, it shows gd. It is attached to the weight with a sticker. ?? On which side to leave the wire, if it is below, then the weight will fall on it later, if it is above, I guess the wire did not allow it to move freely? If you leave the wire up, it turns the acceleration graphs upside down, makes it harder to understand, because you have to turn things upside down in your head. What we can do is to reset the sensor reading, i.e. the initial reading is g. Now free fall means acceleration in one direction, coming up in another direction. Understanding becomes more difficult.

On the graphs, you can see that force and acceleration go exactly in the same rhythm, a reference to the formula F=ma, if they still have time to notice it - the greater the acceleration, the greater the power.

YOU COULD TRY TO DO THIS IN THE SPREADSHEET DO NOT DO THIS: m=F/g, should get a constant.

Another thing that can be noticed - in the event of a collision with the base, the collision time is shorter. The explanation?

The eighth experiment, we measure the acceleration of the weight when it falls against the base. They adjust the height of the force sensor so that when the weight falls, it hits the wooden block on the sponge. Let's measure. Now we see that the force sensor still shows a few newtons, while the acceleration sensor shows up to 300m/s2. If we recalculate it, we get 30g or 3000N, which is a lot.

You can feel it when you hit the base and measure out, for example, 30g. Then if this 30g lasted continuously, would it be so painful all the time? The maximum gd that a person has had to endure.

Conclusions - a fast change in speed means a lot of power. A slow change in velocity, i.e. a small acceleration means a small force. The force from the inertia of the body is what breaks us in collisions.

Our second law of physics - F = ma.
