You are sitting in a car that isn't moving suddenly, the car quickly accelerates. Your body seems to be pushed back against the seat Which word best explains why your body seemed to be pushed backward against the seat? newion gravity vector C inertia

## Step 1<br />The problem is asking us to identify the term that best explains why our body seems to be pushed backward against the seat when a car suddenly accelerates. The options provided are: newton, gravity, vector, and inertia.<br /><br />## Step 2<br />Let's analyze each option:<br />- Newton: This is a unit of force in the International System of Units (SI). It doesn't explain why our body is pushed backward.<br />- Gravity: This is a force that attracts two bodies towards each other. It doesn't explain why our body is pushed backward.<br />- Vector: This is a quantity that has both magnitude and direction. It doesn't explain why our body is pushed backward.<br />- Inertia: This is a property of matter by which it continues in its existing state of rest or uniform motion in a straight line, unless that state is changed by an external force. This explains why our body seems to be pushed backward against the seat when the car suddenly accelerates.<br /><br />## Step 3<br />Based on the above analysis, the term that best explains why our body seems to be pushed backward against the seat when the car suddenly accelerates is 'inertia'.
