Physics

Question 1

Newton’s first law of motion

Answer 1

an object remains at rest or continues to move with the same speed in the same direction unless acted on by an outside, unbalanced force.

Question 2

Newtons second law of motion

Answer 2

how the mass of an object affects the way that it moves when acted upon by one or more forces.
Formula - a=F/m

Question 3

What are two forces acting on a spacecraft

Answer 3

Two forces acting on a spacecraft include the weight of gravity and the upward push of burning fuel. The net force is the difference between the two. As the mass gets smaller (burning fuel) the acceleration increases

Question 4

speed

Answer 4

a measure of how fast or slow an object is moving, the rate of change of distance with respect to time

Question 5

velocity

Answer 5

a measure of the rate of change in displacement.

Question 6

acceleration

Answer 6

the rate of change/increase in speed

Question 7

inertia

Answer 7

newtons first law

The greater the mass of the object, the more inertia it has
