What is occurring from point A to point B?
What was occurring from point B to point C?
Which of the following are vector quantities?
I. Momentum
II. Impulse
III. Velocity
IV. Speed
I and III only
I, II and III only
II and II only
I, III and IV only
What is the definition of the term impulse?
The rate of change of velocity
A force that acts in opposite to the movement of one surface on another
The product of force multiplied by the time during which the force acts
The speed of an object in a given direction
Why would a high jumper arch their back while passing over the bar
To increase the speed at take off
To move their centre of mass outside of their body
To increase moment of inertia
To optimise angle of take off
Newton's First Law States........
Objects at rest tend to stay at rest unless acted on by an outside force.
Objects accelerate often and it is difficult to know when or how they will accelerate.
Objects in motion tend to stay in motion unless acted on by an outside force.
Both A & C
Newton's second law states.....
If there is more mass then there is more acceleration
An object at rest wants to be in motion
Force = Mass x Acceleration
The force exerted on an object is not related to mass or acceleration
Newton's third law states.......
For each action there is a larger reaction associated with it.
None of these choices
For each action there is an equal and opposite reaction.
For each action there is a smaller reaction associated with it.
Stacy is rowing a boat. She wants the boat to move forward. According to Newton's Third Law, in which direction should she move her paddle in the water?
Backwards
Above her head
Forward
East
Which statement best defines fulcrum?

the point on which the load rotates or pivots
Which statement best defines load?
the point on which the lever system rotates or pivots
the point of physical exertion or applied force into the lever system
the point on which an object on the lever system is being moved or repositioned.
the point on which the load rotates or pivots
Which statement best defines effort?
the point on which the lever system rotates or pivots
the point of physical exertion or applied force into the lever system
the point on which an object on the lever system is being moved or repositioned.
the point on which the load rotates or pivots
