SP1 - Motion Flashcards
What is a vector quantity?
Quantities that have both size and direction.
Are forces a vector or scalar quantity?
Vector
What is a scalar quantity?
Quantities that don’t have a direction.
What are examples of scalar quantities?
Distance
Speed
Energy
Time
What is displacement?
The distance covered in a straight line
What is upthrust?
A force that helps objects float.
What is the difference between mass and weight?
Mass is how much matter there is in an object.
Weight is a measurement of the size of the pull of gravity on an object.
What is the formula for weight?
Weight = mass x gravitational field strength
What are examples of vector quantities?
Acceleration
Momentum
Force
What is velocity?
The speed in a particular direction.
What is the units of velocity?
m/s
What is acceleration?
A measure of how fast velocity is changing.
What is momentum?
A combination of mass and velocity.
What’s the equation for average speed?
Speed = distance (m) / time (s)
Is acceleration a vector or scalar quantity?
Vector
