which of newtons laws explains why a test dummy continues forward until it makes contact with another object?
Answer
Brief Explanations:
Newton's first law, also known as the law of inertia, states that an object in motion will stay in motion with a constant velocity unless acted upon by an external force. A test - dummy in a moving vehicle has inertia. When the vehicle stops suddenly, the test - dummy continues forward due to its inertia until it hits another object.
