What is mass?

The amount of matter in an object

100

What is weight

The amount of gravitational force acting upon an object

  • What is inertia?

§Inertia – the tendency of an object at rest to remain at rest, or if moving, to continue moving at a constant velocity.

300

When thinking about free fall ,Who experiences this?

astronauts

300

300

Gravitational force deceases as what increases

distance

400

When playing pool, and your cue ball hits another ball and your cue ball suddenly stops. What happens to its momentum?

It is transferred to the other ball

400
  • What is the definition of momentum?

Momentum is a property of all moving object which is equal to the product of the mass and the velocity of the object

400

What is free – fall?

§When gravity is the only force acting on an object, the object is said to be in free fall.

  • Calculate the momentum of an 8.5 kg man jogging north along the highway at a rate of 2.65 m/s.

225 kg x m/s north

400
  • What is another name for each of the laws of motion?

1st - Law of Inertia

2nd - Law of Acceleration

3rd - Law of Reciprocal Forces or Law of Momentum

500

Momentum is what in a collision

conserved

500
  • Why is projectile motion in a curved path?
because it has horizontal and vertical forces acting upon it
500

Name and state Newton’s Three Laws of Motion. Give examples of each

  • 1st – An object at rest remains at rest and an object in motion maintains its velocity unless it experiences an unbalanced force; sliding a book across a rough surface

  • 2nd – – the unbalanced force acting on an object equals the object’s mass times its acceleration; an empty cart will have a greater acceleration than a heavier cart full of groceries

  • 3rd - For every action force, there is an equal and opposite reaction force; kicking a ball
