Work from the idea of speed to the formula used in class.
Speed tells us how much distance is covered each second.
This is the shorter version of the same formula.

Objective
Check the rule with data.
Method
Push a trolley with different forces.
Model / Data
Class measurements
Assumptions
The trolley track is smooth enough.
Limitations
Timing and friction can change results.
Findings
The results show the same upward pattern.
A line graph showing force on the x-axis and acceleration on the y-axis.
The line goes upward, so acceleration increases when force increases.

Topic: Forces Practical
If the mass stays the same, a bigger force will make the trolley accelerate more.
Forces textbook page
It explains force, mass, and acceleration in simple terms.
Textbook
Doubling force should double acceleration if mass stays the same.
The textbook shows a perfect straight-line model.
Class practical
The 2 N result is a little higher than the perfect line.
The measured value was 2.1 instead of exactly 2.0.
The textbook is a perfect model, but the class practical has friction and timing mistakes.
The class result is still close enough to support the pattern.
