# 20 Practice Questions for Year 11 Physics Module 1: Kinematics

Searching for more practice questions for Year 11 Physics Module 1: Kinematics? Well, luckily, we are here to help you out! Just in case you missed it, we broke down Module 1 in this article here!

We’ve structured these questions for Physics Module 1: Kinematics by breaking them up into two parts (based on each inquiry question). So today we’re going to have a look at motion in a straight line and motion on a plane.

Let’s get into the Physics Module 1 practice questions!

## Motion in a Straight Line

### Question 1

What is the result of subtracting 300m south from 150m north?

Describe uniform straight-line (rectilinear) motion and uniformly accelerated motion through:

• qualitative descriptions
• the use of scalar and vector quantities

(ACSPH060)

### Question 2

Explain, using an appropriate example how the velocity of an object moving at 20ms-1 can change yet still continue to move at 20ms-1.

Describe and analyse algebraically, graphically and with vector diagrams, the ways in which the motion of objects changes, including:

• velocity
• displacement

(ACSPH060, ACSPH061)

### Question 3

A ball is dropped from a height of 2m. What is the magnitude of the ball’s velocity when it is 0.8 m above the ground?

Use mathematical modelling and graphs, selected from a range of technologies, to analyse and derive relationships between time, distance, displacement, speed, velocity and acceleration in rectilinear motion (ACSPH061)

### Question 4

A ball is kicked off the back of a ute traveling at 50 km/h. A child on the street sees the ball hit the pavement and then bounce straight up. What was the velocity of the ball relative to the truck? Assume there is no spin in the ball.

Calculate the relative velocity of two objects moving along the same line using vector analysis

### Question 5

An object is thrown vertically upwards with an initial velocity of 20ms-1. The ball returns its original position after 5 seconds. Sketch a displacement v time graph for the motion of the object. Include relevant displacement values on the graph.

### Question 6

Two trains pass each other on the tracks. The first train is travelling East at 120 km/hr and the second train is travelling at 100km/hr in the same direction. A passenger throws a ball at 20km/hr towards the back of the second train. What is the velocity of the ball relative to the ground?

### Question 7

What is the acceleration of a freely falling object if there is no air resistance? If there is air resistance, how does this affect the previous statement?

Use mathematical modelling and graphs, selected from a range of technologies, to analyse and derive relationships between time, distance, displacement, speed, velocity and acceleration in rectilinear motion (ACSPH061)

### Question 8

A ball is thrown straight up into the air and it feels no air resistance. How can this ball have an acceleration when it stops moving at the highest point?

Use mathematical modelling and graphs, selected from a range of technologies, to analyse and derive relationships between time, distance, displacement, speed, velocity and acceleration in rectilinear motion (ACSPH061)

### Question 9

You throw a piece of playdough straight up towards the ceiling, which is 4.50 m above the point where the playdough leaves your hand. The initial speed of the putty when it leaves your hand is 8.20 ms-1. How much time does it take for the playdough to reach the ceiling?

Use mathematical modelling and graphs, selected from a range of technologies, to analyse and derive relationships between time, distance, displacement, speed, velocity and acceleration in rectilinear motion (ACSPH061)

### Question 10

The travelator in an airport terminal moves at 1.5 ms-1 and is 35.0m long. If someone steps on at one end and walks 1.8 ms-1 relative to the travelator, how much time does it take for her to reach the end of the travelator if she a) walks in the opposite direction? b) in the same direction?

Calculate the relative velocity of two objects moving along the same line using vector analysis

## Motion on a Plane

### Question 11

A plane is travelling North at 140km/hr, and it encounters a side wind travelling East at 50km/hr. What would the resulting velocity of the plane be?

Analyse the relative motion of objects in two dimensions in a variety of situations (ACSPH060, ACSPH132)

### Question 12

A boat traveling East at 5.0 m/s encounters a current traveling North at 3.0 m/s. If the width of the river is 100m wide, what distance downstream will the boat reach the shore?

Analyse the relative motion of objects in two dimensions in a variety of situations (ACSPH060, ACSPH132)

### Question 13

Why is it easier for an aeroplane to take off into the wind rather than against it?

Describe and analyse algebraically, graphically and with vector diagrams, the ways in which the motion of objects changes, including:

• velocity
• displacement

(ACSPH060, ACSPH061)

### Question 14

Someone throws a ball at a wall and this collision occurs over 1s. The initial and final velocity is 5ms-1. The ball hits all wall at an angle of 60 degrees to the wall and it deflects back at the same angle. Calculate the change in velocity.

Describe and analyse algebraically, graphically and with vector diagrams, the ways in which the motion of objects changes, including:

• velocity
• displacement

Person B walks 25m in a direction 60 degrees south of west. They then stop and turn to face each other. What is the distance between them and what direction should person A walk to go directly towards person B?
