What is motion? This is another name for your starting point. What is a reference point? This is the difference between distance and displacement. What is distance is how far you travel and displacement is the distance between where you start and where you end? This is the distance an object moves divided by the time it took to move that distance. What is speed? This is velocity. What is the speed and direction of an object’s motion? This is a force. What is a push or pull on an object? This is the difference between a contact and noncontact force. What is a contact force pushes or pulls an object by touching it and a noncontact force does not touch the object? This is a contact force that resists the sliding motion between two objects that are touching. What is friction? This is a noncontact force that exists between all objects that have mass. What is gravity? This is the difference between balanced and unbalanced forces. What is balanced forces have a net force of 0 Newtons and unbalanced forces have a net force of anything but 0? This represents an object that is not moving on a displacement-time graph. What is a horizontal line? This represents an object slowing down on a speed-time graph. What is line slanting down from upper left to lower right? This represents a constant speed on a speed-time graph. What is a horizontal line? This is found on the xaxis on a displacementtime graph. What is time? This is found on the yaxis on a speed-time graph. What is speed? This is the sum of all the forces acting on a object. What is a net force? A skateboarder moves at 10m/s. After 5 seconds, the skateboarder moves at 20 m/s. What is the skateboarder’s acceleration? What is 2 2 m/s ? If a tug of war team is pulling at a force of 300 N to the left and the other tug of war team is pulling at a force of 400 N to the right, this is the Net Force. What is 100 N to the right? If Sally is pushing Bobby at a force of 400 N forward and Danny is pulling Bobby at a force of 400 N backward, this is the Net Force. What is 0 N ( balanced forces)? These are the units for acceleration and force. What are m/s2 and Newtons (N)? This is the formula for acceleration What is a=Vf -Vi t Gravity, magnetism, and static electricity are examples of this… What are noncontact forces? A car is travelling 55 miles per hour East, I have just describing the car’s… What is velocity? The boy in this picture has moved away from the game to the vending machine, the red line represents his path and the blue line represents his distance from the starting point. This is the word for the blue line. What is his displacement? This explains why a Ferris Wheel spinning at a constant speed can still have a change in velocity. What is because velocity also includes direction, so a change in direction causes a change in velocity?
