FORCES of Motion Vocab Submission

1) a measurement of how much an object speeds up as it falls; Earth = 9.8 m/s/s

• gravitational acceleration
• fluid friction
• friction
• inertia
• Law of Acceleration

2) a way of describing how hard it is to stop an object from moving (dependent on the object's mass and velocity)

• momentum
• fluid friction
• friction
• gravitational acceleration
• inertia

3) any force that works to stop objects motion between two objects that are touching.

• friction
• fluid friction
• gravitational acceleration
• inertia
• Law of Acceleration

4) explains that an object's acceleration is equal to the forces acting on it divided by the object's mass; a.k.a. Newton's 2nd law of motion

• Law of Acceleration
• fluid friction
• friction
• gravitational acceleration
• inertia

5) states that all forces act in equal and opposite pairs (action/reaction forces)

• Newton's 3rd Law of Motion
• fluid friction
• friction
• gravitational acceleration
• inertia

6) states that an object will change its motion (speed up, slow down, stop, start, or turn) if a force is acted on it; a.k.a. Newton's 1st Law of Motion

• Law of Inertia
• fluid friction
• friction
• gravitational acceleration
• inertia

7) the force between two objects as they roll over each other

• rolling friction
• fluid friction
• friction
• gravitational acceleration
• inertia

8) the force between two objects that stops them from "sliding"/slipping (holds objects in place)

• static friction
• fluid friction
• friction
• gravitational acceleration
• inertia

9) the force produced from gases and liquids as an object passes through them

• fluid friction
• friction
• gravitational acceleration
• inertia
• Law of Acceleration

10) the tendency for an object to resist a change in its motion

• inertia
• fluid friction
• friction
• gravitational acceleration
• Law of Acceleration
