P2: Resultant Forces

Question 1

What can force affect?

Answer 1

The shape of an object, its state of rest or its motion.

Question 2

Newton

Answer 2

(N) the unit of force. (10N-1kg)

Question 3

Resultant Force

Answer 3

The combined effect of the forces acting on an object.

Question 4

When the resultant force acting on an object is zero…

Answer 4

It either remains stationary or Continues to move at a constant speed.

Question 5

When the resultant force on an object is not zero…

Answer 5

The movement of an object depends on the size and direction of the resultant force.

Question 6

The Parallelogram of forces

Answer 6

Used to fine the resultant force of two forces that do not act along the same line.

Question 7

resultant force=

Answer 7

Mass x Acceleration

Question 8

How can an object be accelerating but also moving at a constant speed?

Answer 8

If an object is moving at a constant speed, but always changing direction, then it has a velocity rather than a speed.

Question 9

Formula for finding the Parallelogram of Forces

Answer 9

(sine of opposite angles)
