Physics Yr 10

Question 1

Distance

Answer 1

How far an object would have travelled to move from one point to another

Question 2

Displacement

Answer 2

Between any two points is defined as the straight line distance in a given direction. (How far out an object is)

Question 3

Speed

Answer 3

Measure of the rate at which An object moves over a distance

Speed= distance➗time

Question 4

Convert m/s to km/h

Answer 4

Multiply by 3.6

Question 5

Convert km/h to m/s

Answer 5

Divide by 3.6

Question 6

Velocity

Answer 6

measurement of the rate and direction of motion

Calculated by dividing the total displacement by the total time taken

Displacement➗time taken

Question 7

Acceleration

Answer 7

Is a measure of the rate at which it changed speed. Tells u how to quickly the speed changed
the final velocity is less than the initial velocity, acceleration will turn out to be a negative quantity or the rate at which an object slows down.

Acceleration= Vf- Vi➗time

Question 8

Force

Answer 8

Described as a push, pull, or lift on an object

E.g gravity pulling a rock down to earth

Question 9

Equal and opposite forces

Answer 9

The statement means that in every interaction, there is a pair of forces acting on the two interacting objects.
Equal in size
Opposite in direction
Acting on two different objects

Question 10

Mass vs weight

Answer 10

Mass= measured via scales amount of matter in an object 
Weight= gravitational pull force of gravity acting on an object

Question 11

Net force

Answer 11

acting on an object is equal to the mass of the object multiplied by the acceleration of the object,

Net force= Mass x Acceleration

Question 12

1st law

Answer 12

If the net force is zero an object will continue with a constant velocity

Question 13

2nd law

Answer 13

The change in velocity of an object depends on the size of the net force and the mass of the object

A=f➗m
F=ma

Question 14

3rd Law

Answer 14

Net force
