Here is a movie showing how an increase in mass of an object can affect the object`s acceleration.

From the above famous equation you can see that an increase in the mass, m, will reduce the acceleration provided the unbalanced force remains the same.

This is why your car will have a smaller acceleration when it is full of passengers than it would have when empty.

Here is a quick summary poster on acceleration:

Hi Physics lovers!
Use the simulation above to find the frequency of the passing waves.
Press the UP Green arrow to start the wave motion. Pressing it again increases the wave speed while pressing the down arrow will reduce the speed.
If the waves run out just press the pause button and then the RESET button.

Make up a table with headings wavelength, frequency and speed and take some readings.

Check that wavelength multiplied by frequency is equal to the wave speed.

Use this table:
You can click on it and print it off.
