  3. Forces Worksheet 6 SHOWING FORCES. A force can be shown with a vector. A vector is a line with an arrow. It begins with a dot. —¥ The dot shows where the force begins —¥ The length of the arrow shows the amount of force —¥ The arrows shows the direction of the force Example: Each square represents force of ONE NEWTON.

  4. What is force you ask? Well, A force is the push, or pull of an object. • Pushing an object will move it away from the force. Example: When you jump in the air, you push yourself down, off the ground, causing your body to go up. • Pulling an object will move it towards the force. Example: Gravity is a force that pulls everything towards the ...

  5. Key Idea: A force makes things change: the speed, the direction and/or the shape of an object. A force can act as a push, a pull or a twist. Big force, little force A tennis ball is hit with a tennis racket. What does the force of the racket do to the tennis ball? Look at these statements.
