The unit used to measure net force.
Newtons
Any change in an object's location.
Motion
The average speed formula.
Average Speed = Total Distance / Total Time
Explain unbalanced and balanced forces.
Unbalanced Forces - The forces that cause an object's motion to change.
Balanced Forces - Equal forces that don't change an object's motion.
Which law of motion is represented by this situation. A piece of paper lying on a desk will not move unless someone or something moves it.
Newton's 1st law of motion
A plane flying from Los Angeles to New York has a speed of 489 miles per hour. The distance from Los Angeles to New York is about 2445 miles. Solve for the time it takes for the flight.
5 hours
Calculate the total net force if someone is pushing on one side of a box applying 60 newtons of force and someone else is on the other side pushing with 38 newtons force.
22 newtons
Explain each of Newton's laws of motion.
Newton's 1st Law - An object's motion will not change unless an unbalanced force acts on it.
Newton's 2nd Law - An object's force is equivalent to its mass multiplied by its acceleration.
Newton's 3rd Law - Every action has an equal and opposite reaction.
A person drove a car 336 miles west for 7 hours. Calculate his velocity.
48 miles per hour west
Force > 490
Which law of motion is represented by this situation. Pushing a car requires less force than pushing a truck.
Newton's 2nd law of motion
Explain speed, velocity, and acceleration.
Speed - The distance an object travels for every unit of time.
Velocity - Speed in a certain direction.
Acceleration - The rate of change of velocity.
Solve for the direction of movement if there is one person at the back of a box pushing the box with a force of 48 newtons while another person is at the front pulling with a force of 56 newtons.
Forward
Which law of motion is represented by this situation. When rowing a boat, we paddle our boat, which pushes water backward, moving the boat forward.
What does a truck slowing down to stop at a red light represent?
Acceleration
