How many laws of motion did Isaac Newton write about?
2
4
3
1
Newtons first law is also referred to as the Law of Inertia. What does inertia mean?
How much something weighs.
A property of matter that causes it to resist changes in velocity.
The speed of an object in a specific direction.
An objects change in velocity.
Which person has a greater inertia?
What would cause the greatest acceleration - hitting a tennis ball with a Tennis racquet or table tennis bat?
Table Tennis bat
Tennis Racquet
What does sequential force summation mean?
The production and combination of forces from different parts of the body to work together at the same time. Typically largest to smallest.
Hitting the ball as hard as you can.
The total momentum of two objects before a collision is equal to the total momentum of two objects after a collision.
The rate of change of velocity of an object with respect to time.
What is the formula to work out velocity?
Velocity = mass X acceleration
Velocity = distance / time
How far an object travels
Velocity = displacement / time
You walk from home to the shop in 100 seconds, what is your speed and what is your velocity?
Speed = 2.2 m/s Velocity = 1.3 m/s East
Speed = 5 m/s Velocity = 4.3 m/s North
Speed = 2.2 Velocity = 1.3
Speed = 3.8 m/s Velocity = 7 m/s East
In this picture who is more stable? The goalie or the kicker?
Kicker
Goalie
Both have the same stability
If you go surfing and want to increase your stability, how would you go about that?
Raising your centre of gravity and increasing your base of support.
There is nothing you can do whilst surfing that will increase your stability.
Lowering your centre of gravity and decreasing your base of support.
Lowering your centre of gravity and increasing your base of support.
Is something trying to maintain a handstand an example of static or dynamic equilibrium?
Balance
Static
Dynamic
Both
What is the definition of dynamic equilibrium?
Travelling at a constant speed in the same direction
Maintaining balance whilst stationary
Maintaining balance whilst constantly moving
What does Newtons third law of motion state?
The acceleration of an object is dependent upon two variables - the net force acting upon the object and the mass of the object.
An object will remain at rest or unchanged unless acted upon by an external force.
If you don't wear a seat belt, you will continue to move once the car has stopped.
Every action has an equal and opposite reaction.
If a cyclist is travelling at a constant velocity and collides with a curb, what will happen to the rider?
He will continue to travel over the curb.
He will stop with the bike.
He will fall backwards.
Can you be charged if you are sent a sexually explicit image to your phone and show another individual?

Yes but you will just get a warning.
Yes it is a chargeable offence.
No because you were never going to send it anyway.
No because the person is over 18.
You are in a relationship and your partner has given you written permission to distribute a sexually explicit photo of them to a friend. Your partner is under 18. Is distributing the photo still a crime?
No, you have their permission.
No, because they trust you.
It isn't a crime, it is just an official warning.
Yes, as the individual is a minor.
