2

What is linear kinematics?

Linear kinematics is the study of motion of objects in a straight line.

New cards

3

What is rotational kinematics?

Rotational kinematics is the study of motion of objects that rotate around a fixed axis.

New cards

4

What is force?

Force is a push or pull that can cause a change in motion.

New cards

5

What is torque?

Torque is the force that causes an object to rotate about an axis.

New cards

6

What is mass?

Mass is the amount of matter in an object.

New cards

7

What is moment of inertia?

Moment of inertia is the resistance of an object to rotational motion.

New cards

8

What is acceleration?

Acceleration is the rate at which an object changes its velocity.

New cards

9

What is angular acceleration?

Angular acceleration is the rate of change of angular velocity with respect to time.

New cards

10

What is the equation for Fnet?

Fnet = ma

11

What is the equation for Tnet?

Tnet = Ia

New cards

12

What is velocity?

Velocity is the speed and direction of an object's motion.

New cards

13

What is angular velocity?

Angular velocity is the rate of change of angular displacement with respect to time.

New cards

14

What is angular displacement?

Angular displacement is the angle through which an object rotates.

New cards

15

What is the relationship between linear and angular motion?

The linear velocity and acceleration of a point on a rotating object are equal to the product of the angular velocity and acceleration and the radius of the circle.

New cards

16

What is center of mass?

Center of mass is the point in an object or system that moves as if all the mass were concentrated at that point.

New cards

17

What is the formula for calculating center of mass?

COM = (m1r1 + m2r2 + ... + mn rn) / (m1 + m2 + ... + mn)

New cards

18

What is the right-hand rule?

The right-hand rule is a rule used to determine the direction of torque.
