If the force of friction is 10N and the Normal force is 20N the coefficient force is..?

0.5N (final force=M x normal force)

Which variable is in both Kinatic and Newton's second law?

A (acceleration)

Objects in rest will remain at rest unless...?

A force acts upon an object

The law of inertia applies too..?

Both moving and non-moving objects

Force causes..?

Changes in motion

What is Newton's second law?

F= m x a

Zero net force means an object isn't moving.

False

Accelerations are produced by...?

Forces

What is the law of inertia?

Inertia is the tendency of objects in motion to stay in motion, and objects at rest to stay at rest unless a force causes its speed or direction to change.

What is Newton's first law?

Newton's first law states that every object continues in a state of rest, or of uniform speed in a straight line, unless acted on by a nonzero net force.

Zero net force means an object isn't accelerating.

True

An object following a straight line path at constant speed..?

isn't acceleration

If the force of gravity suddenly stopped acting on the plants, they would...?

move at a constant velocity

Compared to its mass on Earth, the mass of a 10kg object on the moon is?

the same(the mass stays the same)
