Newton's 3rd Law | arrow_right_alt | An object in motion will stay in motion and an object at rest will stay at rest unless an unbalanced force acts on it |
Newton's 1st Law | arrow_right_alt | The Force of an object is determined by the mass of the object and its acceleration. |
Newton's 2nd Law | arrow_right_alt | Every action force has an equal and opposite reaction |
A small force is applied to a toy car and it travels a distance of 1.5 meters. If I apply a larger force to the same toy car, what do you predict will happen to the distance traveled by the car.

How far away is the dog after 4 seconds?
What is the dog's speed at 8 seconds?
What is happening to this object over time?
What is happening to this object over time?
Slowing down to 5 m/s is acceleration.
Acceleration only occurs if an object is increasing in speed.
A car maintaining the same speed as it drives around a turn is experiencing acceleration.
