Forces and Motion

Net force combines all forces. A non-zero net force changes velocity; balanced forces produce no acceleration.

What to remember

  • Balanced forces have net force zero.
  • Unbalanced forces can accelerate objects.
  • Friction opposes relative motion.
  • Gravity acts at a distance.
  • Force has magnitude and direction.

Key words

net force — vector sum of forces
balanced — net force zero
unbalanced — net force non-zero
friction — contact force opposing motion
gravity — attractive force between masses
How to use this drill: review the short notes when learning, then close them on later attempts and practise from memory. The rotating bank delays a full set repeat for 25 attempts on the same browser.

What this Year 7 / Grade 7 science drill practises

Reason with balanced and unbalanced forces. This daily drill is designed as short retrieval practice rather than a complete course. It can be used for school revision, homework, warm-ups or independent practice.

  • Balanced forces have net force zero.
  • Unbalanced forces can accelerate objects.
  • Friction opposes relative motion.
  • Gravity acts at a distance.
  • Force has magnitude and direction.

International use: the topic is organised by broadly useful school-level progression. Exact curriculum timing and terminology can vary between countries, states and schools.
