Why Do Heavier Objects Not Fall Faster?

Why Do Heavier Objects Not Fall Faster?

Foundational Physics Short Answer: Without air resistance, heavier and lighter objects fall with the same acceleration. Gravity pulls harder on a heavier object, but that object also has more inertia, so its greater weight does not make it accelerate faster. Sensei’s...
Why Does Direction Matter for Velocity but Not Speed?

Why Does Direction Matter for Velocity but Not Speed?

Foundational Physics Short Answer: Direction matters for velocity because velocity describes both how fast and which way an object moves, while speed describes only how fast. Two objects moving equally fast in opposite directions have the same speed but different...
Why Is Acceleration Measured in m/s²?

Why Is Acceleration Measured in m/s²?

Foundational Physics Short Answer: Acceleration is measured in meters per second squared (m/s²) because it tells us how much velocity, measured in meters per second, changes each second. Sensei’s WarningThe second in m/s² does not mean the object travels for two...
