Force and Newtons

Question 1

Force =

Answer 1

ma (mg)

Question 2

1 Newton =

Answer 2

1kg*m/s^2

Question 3

Describe the force of gravity

Answer 3

Attractive force between two masses, proportional to eachother; all matter attracts other matter

Question 4

Describe electromagnetic force

Answer 4

Force experienced by charge in electric fields; normal force, friction, tension

Question 5

Normal Force

Answer 5

Perpendicular force exerted by surfaces to prevent penetration

Question 6

Friction

Answer 6

Resists motion between contacting bodies; pushing against the direction of movement

Question 7

Tension(Ft)

Answer 7

Pulling force exerted by string or rope; transmits force along paths or angles

Question 8

Centripetal force (Fc)

Answer 8

Causes circular or elliptical motion; gravity, tension

Question 9

Springs

Answer 9

Exert force when stretched or compressed; push back or pull against deformation

Question 10

Newtons first law (law of ___)

Answer 10

Law of Inertia:
Objects at rest remain at rest; objects in motion maintain constant motion unless acted on by an external force

Question 11

What is Inertia

Answer 11

Resistance to changes in motion; proportional to mass

Question 13

Newtons third law (___ and ___)

Answer 13

Action and Reaction
For every action, there is an equal and opposite reaction (Fa on B = -Fb on A)
Forces always occur in pairs between two interacting objects

Question 14

Larger mass means ___ acceleration

Answer 14

Less
