newtons law of motion

• What do Newton's Laws of Motion describe?

  The effects of forces on motion
• What are the three laws of motion called?

  1. Newton's First Law
  2. Newton's Second Law
  3. Newton's Third Law
• What happens if the resultant force on a stationary object is zero?

  The object will remain stationary
• What occurs if the resultant force on a moving object is zero?

  The object continues moving at the same velocity
• What is the definition of velocity in this context?

  Speed in a specific direction
• What does a balanced force on a stationary object indicate?

  The resultant force is zero
• What happens to an object with no forces acting on it?

  It maintains its speed and direction
• What is the resultant force when two equal forces act in opposite directions?

  The resultant force is zero
• What is the driving force of a car moving at a constant speed?

  The engine's force acting to the left
• What are resistive forces?

  Friction with air and road
• What happens when a resultant force acts on a stationary object?

  The object accelerates in the direction of the force
• What does a resultant force cause an object to do?

  Change its speed or direction
• What happens when a resultant force acts on an object moving at constant speed?

  The object decelerates if the force opposes motion
• How does a resultant force affect an object's direction?

  It can change the object's direction
• What is the speed of the car mentioned in the video?

  15 m/s
• What is the effect of a resultant force acting upwards on an object moving at constant speed?

  It causes the object to accelerate upwards
