Forces Forces have size and direction and are expressed in Newtons (N) Force is always exerted by one object on another object Balanced forces produce no change in motion Unbalanced forces produce a change in motion Instructional Approach(s): The teacher should present the information on the slid...
Unbalanced forces Motion will change when the forces are unbalanced Forces are unbalanced when: Start moving (pedalling fast and hard) Speed up (pedalling fast and hard) Slows down (using the brakes) Comes to a stop (using the brakes) Changes direction (turning the handle bars) Note that ...

Grade 3: Forces Causing Motion by Tracy Bellaire (eLesson Plan eBook)Bellaire,Tracy
the motion of falling objects when the only force acting on it is gravity. Acceleration due to the force of gravity is 9.8 m/s/s. The size of the force depends on mass (matter, doesn’t change) and distance. The gravitational force Earth exerts on an object is the weight ( is a fo...
Newton’s 1st Law Newton’s First Law: an object at rest will remain at rest and an object in motion maintains its velocity unless it experiences a net force. Also known as inertia. Newton’s 1st Law An object with a greater mass has a greater inertia; therefore, a larger force will ...
Sliding friction is the force that works against the motion of two surfaces that are sliding across each other. caused by the microwelds breaking and then forming again Rolling friction is the frictional force between a rolling object and the surface it rolls on. Caused when the object and sur...
