Motion and Time
Science · Grade 7 · Week 13 · 25 questions
Forces make things move, stop, speed up, slow down, or change direction. Understanding forces and motion is the foundation of physics and explains how the physical world works.
What you'll practise
- Identify different types of forces
- Explain Newton's laws of motion
- Calculate force, mass, and acceleration
- Understand friction and its effects
