The body is faced with opposing forces such as; (select 4)

• Gravity

• Pull

• Air resistance

• Water Resistance

• Friction

The greater the force applied to an object, the greater the

• speed and acceleration of that object

• mass of that object

• velocity of that object

• resistance to that object

As the mass of an object increases, so does the

• power required to move it

• acceleration

• force required to move it

• speed

If two forces are equal, what is the result?

• small movement will occur

• no movement will occur

• great movement will occur

Which of the following is not an example of equal forces in sport?

• Scrum

• Arm Wrestle

• Layup

Newtons first law is that a body will remain at rest or in uniform motion in a straight line until an external force acts upon it to change it state of motion. Which of these is a sporting example?

• Tumble turn in swimming

• Beam routine in gymnastics

• a goal kicked in afl

• a ball pitched in baseball will travel towards the batter until struck

A sprinter applies force against the block , which is equal to the force that propels him forward. This is an example of which of newtons laws?

• 1st law: an object remains at rest or will move at a constant velocity, unless acted upon by an external force

• 2nd law: the acceleration of a body is directly proportional to, and in the same direction as, the force acting on the body

• 3rd law: for every action there is an equal and opposite reaction

The tendency of an object to maintain its state of motion. A greater mass will require a greater force to move and a greater force to stop

• mass

• weight

• intertia

• velocity

The rate of change of velocity. A swimmer shows this when they move from stationary into a dive

• Speed

• Acceleration

• Friction

• Velocity

Force that is acting upon another object is

• reaction force

• applied force
