Flashcards do conjunto (14)
- 1What is linear motion?Movement where all parts of an object travel the same distance in the same direction at the same time
- 2What is a scalar quantity?Something that is only considered in terms of size or magnitude
- 3What is a vector quantity?Something considered in terms of both magnitude and direction
- 4Give 3 examples of scalar quantities1. Speed
2. Distance
3. Mass - 5Give 6 examples of vector quantities1. Velocity
2. Acceleration
3. Weight
4. Momentum
5. Displacement
6. Impulse - 6Define speed and how it is calculatedA body's movement per unit of time.
Distance ➗time = speed (m/s) - 7Define velocity and how it calculatedThe speed of a body in a given direction
Displacement ➗ time = velocity (m/s) - 8Define acceleration and how it is calculatedThe rate of change in velocity
Velocity ➗ time = acceleration (m/s^2) - 9Define massThe quantity of matter that a body possesses
(Kg) - 10Define weight and how it is calculatedThe force of gravity exerted on the mass of a body
Mass ✖️ gravity = weight (newtons) - 11Define distance and how it is calculatedThe measure of a path travelled by an object
Speed ✖️ time = distance (m) - 12Define displacementThe shortest possible route from A to B in s straight line
- 13Define momentum and how it is calculatedThe amount of motion a body possesses
Mass ✖️velocity = momentum (Kgms) - 14Define impulse and how it is calculatedThe length of time a force is applied to an object, relating to a change in momentum
Force ✖️time
