Speed Flashcards
Instantaneous speed
Instantaneous speed is the speed of an object at a given moment.
How to get the avg of speed
avg=total distance/total time
How to find speed
speed=distance/time
What is velocity
Velocity is the speed an object travels at a certain direction
How to find velocity
velocity= displacement/time
How to find average velocity
initial v+final v / 2
What is acceleration
The rate of change in velocity in a direction
How to find acceleration
acceleration= change in velocity/time
What is force
it is push or a pull in a particular direction
Weight
the force by which the earth pulls a body to the centre
Mass
the measure of the amount of matter an object has
Distance
how far an object moves
Energy
the ability to do work
How to find speed
Speed=distance/time
Displacement
Is the distance travelled in a particular direction
How is distance a scalar quantity
It is because it has magnitude but no direction .
List Any two physical quantities that are scaler
Mass,speed
What is the unit for force
SI
Momentum
The product of mass and energy, the direction is the same as the velocity
