5th - Science Unit 3 Lesson 1 Vocab & study Guide

Question 0

A change in an object’s position over time.

Answer 0

Motion

Question 1

The location of an object

Answer 1

Position

Question 2

A group of objects from which a position or a motion is measured

Answer 2

Frame of Reference

Question 3

How fast an object’s position changes with time at any given moment.

Answer 3

Speed

Question 4

The speed and the direction of a moving object.

Answer 4

Velocity

Question 5

A change in velocity with respect to time.

Answer 5

Acceleration

Question 6

The mass of an object multiplied by its velocity.

Answer 6

Momentum

Question 7

What are the two parts of motion

Answer 7

Distance and Direction

Question 8

How do you calculate speed, velocity and acceleration

Answer 8

Speed = distance / time traveling
Velocity = speed x distance
Acceleration = change in speed / time

Question 9

What units do we use to measure speed

Answer 9

Miles per hour, meters per second, kilometers per hour, and feet per second

Question 10

Compare and contrast speed and velocity

Answer 10

Speed is how fast something goes well velocity is the measurement of speed

Question 11

What are the units for acceleration

Answer 11

(M/s)/s

Question 12

What is it when an object loses speed

Answer 12

Deceleration

Question 13

What is the tendency of an object to move in a straight line

Answer 13

Inertia

Question 14

How do you find an objects momentum

Answer 14

Product of mass multiplied by velocity

Question 15

What is the relationship between mass and inertia

Answer 15

As the mass of an object increases the inertia increases

Question 16

Give into objects be able to explain, using concept of momentum, which could be harder to stop

Answer 16

An object with more mass would be harder to stop
