force, motion and energy

Question 1

define force

Answer 1

a force is a push or pull upon on object resulting from the objects interaction with another object.

Question 2

define motion

Answer 2

change with time of the position or orientation of a bodymotion is the phenomenon in which an object changes its position with respect to time.

Question 3

define acceleration

Answer 3

acceleration is a vector quantity that is defined as the rate at which an object changes its velocity. An object is accelerating if it is changing its velocity.

Question 4

true or false: the speed of an object depends on the direction it’s traveling ?

Answer 4

false

Question 5

what is the velocity of an object?

Answer 5

the speed and direction the object is moving.

Question 6

what is the equation of acceleration?

Answer 6

A = final velocity - initial velocity / time
or
A = v - u / t

Question 7

that is the formula to calculate distance?

Answer 7

speed x time

Question 8

what is the formula to calculate time?

Answer 8

distance / speed

Question 9

what is the speed formula?

Answer 9

distance / time

Question 10

what is newton’s first law of motion?

Answer 10

the inertia theory; all objects will remain moving in the same direction at the same speed unless acted upon by an external force.

Question 11

what is newtons 2nd law of motion?

Answer 11

f=ma theory; the heavy the mass of an object the more force will be needed to accelerate.

Question 12

what is newtons 3rd law of motion?

Answer 12

every action has an equal and opposite reaction.
