Force and motion Kinds of force effects of fornce

1. FORCE & MOTION

2. FORCE
• PUSH OR PULL ON OBJECTS WITH MASS
WHICH CAUSES THE OBJECT TO CHANGE
DIRECTION AND SPEED (VELOCITY)
• HAS MAGNITUDE AND A DIRECTION
• is measured in N or Newtons
• F = m x a; mass x acceleration
• How can motion be described
• change in direction
• change in speed

3. The Force has different
effects, and here are some of
them.
• Force can make a body that is at
rest to move.
• It can stop a moving body or slow it
down.
• It can accelerate the speed of a
moving body.
• It can also change the direction of
a moving body along with its shape
and size.
