Forces and Newton's laws
Resolve forces; apply Newton's first, second and third laws to particles; friction and connected particles
What you'll learn
- 1
Imagine you're pushing a heavy shopping trolley 🛒. The harder you push, the faster it goes — that's Newton's 2nd Law in action!
- 2
What happens to a trolley's acceleration if you push it twice as hard?
- 3
Drag the force slider to see how it changes the acceleration of a 10 kg object.
- 4
A 5 kg ball is pushed with 20 N of force. What's its acceleration?
- 5
A 2 kg book is pushed with 10 N. Find its acceleration using the formula.
- 6
What is the acceleration of a 3 kg object pushed with 15 N?
- 7
If you double the mass but keep the force the same, what happens to acceleration?
