newtons laws

Cards (8)

  • the force on an object is the product of its mass and acceleration
  • Newton's first law of motion states that if the resultant force acting on a stationary object is zero, then the object will remain stationary
  • If the resultant force acting on a moving object is zero, then the object will continue moving in the same direction at the same speed, with the same velocity
  • The velocity of an object will only change if a resultant force is acting on the object
  • Resistive forces, such as friction with the air and friction with the road, act as equal and opposite forces to maintain a constant speed of a moving object
  • A resultant force of 50 Newtons acting on a stationary object will cause the object to accelerate in the direction of the force
  • A resultant force of 50 Newtons acting on a moving object will cause the object to decelerate, leading to a slowdown
  • A resultant force can also change an object's direction, causing it to accelerate in a different direction
