Net Force

The vector sum of all forces acting on an object; if forces act in the same direction, they are added; if opposite directions, they are subtracted; it determines the object's acceleration.

2
New cards

Balanced Forces

Forces whose net force on an object is zero; the object either remains at rest or continues moving at a constant velocity.

3
New cards

Unbalanced Forces

Forces whose net force on an object is not zero; they cause acceleration or a change in motion.

4
New cards

Newton's First Law

An object at rest stays at rest, and an object in motion stays in motion with a constant velocity unless acted on by an unbalanced force.

5
New cards

Object at Rest

An object that is not moving; if forces are balanced, it will remain at rest.

6
New cards

Object in Motion

An object that is moving with constant velocity when forces are balanced.

7
New cards

Acceleration

The rate of change of an object's velocity; according to Newton's second law, acceleration equals net force divided by mass (a = F/m).

8
New cards

Mass

A measure of the amount of matter in an object; mass affects how much an object accelerates for a given net force (larger mass = smaller acceleration for the same net force).

9
New cards

Force

A push or pull on an object; a vector quantity with both magnitude and direction.

10
New cards

Friction

A force that opposes motion between two surfaces in contact; can slow motion (negative acceleration) but is useful for stopping or gripping.

11
New cards

Newton's Second Law

Acceleration of an object equals the net force acting on it divided by its mass (a = F/m); also expressed as F = m a.

12
New cards

Three-Point Seatbelt

A seatbelt design with two straps joined at three points to restrain both upper and lower body; top strap over the shoulder, bottom strap near the hips; designed to be secure with one hand.

13
New cards

Criteria

Design requirements that a solution must meet; what the solution should achieve.

14
New cards

Constraints

Design limits or restrictions on a solution, such as cost and ease of manufacture.

15
New cards

Inertia

The resistance of any physical object to a change in its state of motion or rest.
