What is the difference between distance and displacement?

Distance is the total length traveled, while displacement includes direction.

How is speed different from velocity?

Speed indicates how fast an object is moving.

Acceleration measures how fast velocity changes.

Gravitational acceleration on Earth is -9.8 meters per second squared, always decreasing velocity.

Projectile motion involves objects moving under gravity's influence, typically ignoring friction.

Displacement considers both the distance and direction an object has traveled, while distance only refers to the total length covered, lacking directional information.
Newton's first law emphasizes that objects in motion remain so unless acted upon by a force, illustrating the concept of inertia and the necessity of external influences to alter an object's state of motion.

Distance is the total length traveled, while displacement includes direction.
Displacement is the difference between final and initial positions.
Distance is a scalar quantity, only magnitude, while displacement is a vector quantity with magnitude and direction.
Speed indicates how fast an object is moving.
Speed formula: d = vt (distance = speed x time).
Average speed is total distance divided by total time.
Velocity includes direction, making it a vector quantity.
Acceleration measures how fast velocity changes.
Acceleration formula: (final velocity - initial velocity) / time.

Acceleration rate is 4 meters per second squared, meaning velocity increases by 4 meters per second every second.
Formula for calculating final velocity: v final = v initial + 80.
Object speeds up if acceleration and velocity have the same sign, slows down if they have opposite signs.
Gravitational acceleration on Earth is -9.8 meters per second squared, always decreasing velocity.
Gravitational acceleration affects vertical velocity, not horizontal velocity.
Projectile motion involves objects moving under gravity's influence, typically ignoring friction.
One-dimensional projectile motion in the y direction involves objects moving up and down.
Two-dimensional projectile motion involves objects moving in both x and y directions.
In projectile motion, horizontal velocity (v x) remains constant unless acted upon by a force.
Vertical velocity (v y) changes due to gravitational acceleration, decreasing by 9.8 meters per second every second.

Initial velocities are v x = 8 m/s and v y = 29.4 m/s at time zero.
One second later, v x remains at 8 m/s while v y decreases by 9.8 m/s due to gravity.
Two seconds later, v x is still 8 m/s, and v y is now 19.6 m/s.
At three seconds, v y reaches its peak at 0 m/s, while v x remains at 8 m/s.
Newton's first law states that objects at rest stay at rest unless acted upon by a force, while objects in motion continue unless a net force is applied.
