CCEA Physics unit 1 solutions

Acceleration

Acceleration is how quickly the velocity is changing whether it be speed, direction or both. Acceleration is a measure of how quickly the velocity of an object is changing.

Demo

In this tutorial you will learn how to calculate the acceleration of a moving object.

The equation is written like this:

$a = { v \unicode{x2013} u \over \text{t}}$

Chilled practice question

Calculate the acceleration if the velocity increases from 4 m/s to 76 m/s in 8 s.

Frozen practice question

How long does it take for the velocity of a bus to increase from 12 m/s to 20 m/s if it is accelerating at 4 m/s2.

Science in context

Acceleration is how quickly the velocity is changing whether it be speed, direction or both.

Speed

Speed is how fast an object is moving in no given direction. Velocity is how fast an object is moving in a given direction. In physics, you can calculate the average speed by taking the total distance travelled and dividing it by the total time required to travel that distance.

Demo

In this tutorial you will learn how to calculate the speed of an object, velocity is speed with direction for example 20 m/s north.

The equation is written like this:

$S = { \text D / T}$

Chilled practice question

Calculate the speed of a car which travels 2000 m in 400 s.

Frozen practice question

How long does it take a car to travel 360 m at 12 m/s ?

Science in context

Speed is how fast an object is moving in no given direction. Velocity is how fast an object is moving in a given direction.
