What happens to the distance travelled when the force increases? Predict the distance travelled when a force of 50 N is applied. Explain why increasing the force changes the motion of the trolley.

For every $10 \text{ N}$ increase in force, the distance travelled increases by approximately $1.5 \text{ m}$.

• $10 \text{ N} \to 1.5 \text{ m}$
• $20 \text{ N} \to 3.0 \text{ m}$
• $30 \text{ N} \to 4.5 \text{ m}$
• $40 \text{ N} \to 6.0 \text{ m}$

Following the pattern, for a force of $50 \text{ N}$ (which is $10 \text{ N}$ more than $40 \text{ N}$), the distance travelled will be:

Increasing the force changes the motion of the trolley because, according to Newton's Second Law of Motion ($F = ma$), a larger net force applied to an object of constant mass results in a greater acceleration. This increased acceleration means the trolley's velocity changes more rapidly, causing it to cover a greater distance in the same amount of time.
