### Motion

1. 1. Motion painincorporated.com Motion Sarah Jones
2. 2. Distance and Displacement
3. 3. Distance is a scalar quantity – it has a size but not direction. Displacement is a vector quantity – it has both size and direction. Travelling from point A to point B and returning to point A - your displacement upon returning is zero. vanilamilo.wordpress.com
4. 4. Speed is a measure of how fast something moves. Calculating Distance distance = average speed x time d = v x t
5. 5. Instantaneous Speed • Your speed at a particular instant. www.dailymercury.com.au
6. 6. Velocity • The rate at which displacement changes. • You can drive a car at a constant speed of 60 km/h, however, every time you change direction, your velocity changes too.

11. 11. Acceleration The rate of change in velocity.
12. 12. The formula can be rearranged to calculate the final speed: final speed = initial speed + (ave. accel. x time taken) v = u + at

15. 15. Isaac Newton’s Laws myfacade.com
16. 16. Newton’s First Law The Law of Inertia - An object at rest will remain at rest unless acted on by an unbalanced force. An object in motion continues in motion with the same speed and in the same direction unless acted upon by an unbalanced force.
17. 17. Inertia The truck has brakes, the massive rock you are transporting does not.
18. 18. Newton’s Second Law Acceleration is produced when a force acts on a mass. The greater the mass (of the object being accelerated) the greater the amount of force needed (to accelerate the object). Force = mass x acceleration F = ma
