Science Forces and Magnets Year One Science | Forces and Magnets | Pushes and Pulls | Lesson 1

Success Criteria • I can name different forces. • I can identify if forces are balanced or unbalanced.

Activity 3 a Using your computer or tablet to help, match up the forces with their correct definitions on the following slide.

Different Types of Forces Force on the ground or against something else during motion (movement) Upwards force from liquid or gas Force that makes objects fall to the ground Force that works against or opposite other forces like gravity or some types of friction

Equal and opposite forces In this example of a tug-of-war, the forces are equal and there is no movement. Only when one force is bigger than the other will the teams begin to move.

Equal and opposite forces The mug is stationary on the table. This means the forces acting downwards and upwards are equal and cancel each other out.

Equal and opposite forces When the person is standing still on the ground, the force acting downwards and the force pushing back upwards are equal.

Equal and opposite forces Whilst the ball is moving upwards the upward force is greater than the downward force of gravity. Some air resistance will also be slowing the ball down.

Activity 3 b On the next slide, label the forces in action and identify if the forces are balanced or if one force is stronger than the other.

Activity 3 b 1. Paraglider

Activity 3 b 2. Ship on water

Activity 3 b 3. Leaves falling to the ground

Activity 3 b 4. Going down a slide
