SI unit for displacement
meter
2 units for velocity
Any 2: m/s, km/h, miles/h, cm/s
m/s2
SI unit for force
Newton
Unit for weight
Newton
2 types of motion based on direction
Linear and rotational
Definition of velocity
Change of displacement over time
Definition of acceleration
Change of velocity over time or (v-u)/t
2 wide category of Force
Force that cause objects to fall to the ground
A speedometer measures the _____________ speed of a car
Average velocity
Total displacement over total time taken
Another word for slowing down
Decelerate
Tendency of an object to remain at rest or, if in motion, to continue moving in a straight line at uniform velocity
Force that opposes motion of an object when 2 surfaces are in contact with each other
Friction
72 kph in m/s
20 m/s
Velocity of a stationary object
The acceleration of a car moving at constant speed
Zero
What is "a" in the equation F=ma?
A type of force that results from difference of densities of an object and the fluid surrounding it
Upthrust/buoyant force
Area under speed vs time graph
Total distance travelled
Area under velocity vs time graph
Total displacement
How to find acceleration from a velocity versus time graph
Gradient/slope of the graph
3 things an unbalanced applied force change in the object the force is applied on
Speed, direction, shape
Type of force used in old television (cathode ray tubes) and displays in hospitals
Electric force
