forces - Newton’s first Law of Motion

Question 1

what does Newton’s Laws of Motion describe?

Answer 1

the effects that forces have on the motion of an object

Question 2

what is Newton’s first Law of motion?

Answer 2

• if resultant force acting on a stationary object is 0, then object will remain stationary
• if resultant force acting on a moving object is 0, then object will continue to move in the same direction at same speed (with same velocity).

Question 3

what happens if forces are the same?

Answer 3

they are balanced so no resultant force?

Question 4

when will the velocity if an object change?

Answer 4

if resultant force is acting on the object

Question 5

what are resistive forces?

Answer 5

an equal force in the opposite direction. they include friction with air and road in a car. they slow down an object

Question 6

what does a resultant force cause?

Answer 6

an object’s speed to change and or direction

Question 7

what happens if object is moving at a constant speed to the right but a resultant force acting to the left?

Answer 7

object will decelerate

Question 8

what happens if an object is moving to the right and then a resultant force also to the right?

Answer 8

it will accelerate

Question 9

what happens if resultant force acting on the bottom of the object?

Answer 9

causes object to accelerate upwards
