Practice Force in Physics

Use these practice problems to test your method after reviewing the concept explanation and worked examples.

Quick Recap

A push or pull interaction between two objects that can cause a change in an object's velocity (speed or direction), described as a vector quantity measured in newtons.

Anything that makes something move, stop, speed up, slow down, or change direction.

Example 1

easy
A 5 \text{ kg} box is pushed across a floor with a force of 20 \text{ N}. If there is no friction, what is the acceleration of the box?

Example 2

medium
Two forces act on an object: F_1 = 15 \text{ N} to the right and F_2 = 8 \text{ N} to the left. What is the net force on the object?

Example 3

easy
A force of 12 \text{ N} acts on a 3 \text{ kg} object. What acceleration does the object experience?

Example 4

medium
A 2.5 \text{ kg} drone speeds up from 4 \text{ m/s} to 10 \text{ m/s} in 3 \text{ s} while flying straight. What net force acts on the drone?
