Motion

Question 1

Force, Mass and Acceleration

Answer 1

Force = Mass*Acceleration, Mass = Force/Acceleration, Acceleration = Force/Mass

Question 2

Distance, Speed and Time

Answer 2

Distance = Speed*Time, Speed = Distance/Time, Time = Distance/Speed

Question 3

Distance

Answer 3

Distance is a scalar quantity that refers to how much space has been covered since the starting point

Question 4

Displacement

Answer 4

Displacement is a vector quantity that refers to how far from the starting point the object has moved regardless of a change in direction.

Question 5

Scalar and Vector Quantities

Answer 5

A scalar quantity is a 1 dimensional measurement of quantity such as distance or weight while vector quantity has more than 1 number. An example of a vector quantity is velocity as it was a magnitude (speed) and a direction.

Question 6

Speed

Answer 6

A scalar quantity as it is a measure of how fast distance is covered not the direction

Question 7

Velocity

Answer 7

A vector quality which measures the speed of something as well as the direction. For example 20km/hr north.

Question 8

Negative and Positive

Answer 8

If an object moves back and forth, 1 direction is considered positive and the other negative. It must be stated which is which but usually right is considered positive.
