Physics P5 - Space for Reflection

?
This is not important when looking at speed, mass, temperature, time, and length.
Direction
1 of 34
The measure of motion that considers both speed and direction.
Velocity
2 of 34
A quantity that only has a number.
Scalar
3 of 34
A quantity that has a number and a direction.
Vector
4 of 34
The vector measurement of distance.
Displacement
5 of 34
Why cars that are travelling at the same speed and in the same direction as you seem to be not moving, whereas car travelling in the opposite direction seem to be travelling a lot faster than they actually are.
Relative Speed
6 of 34
What you do with two vectors to find the resultant (remembering signs).
Add
7 of 34
If a force is travelling in the opposite direction to the object moving, this is what it becomes - shown on a diagram by drawing the arrow in the opposite direction.
Negative
8 of 34
The shape that you use to work things out when an object is travelling across the force.
Triangle
9 of 34
The maths that you use to work things out when an object is travelling across the force (at a right angle).
Trignometry
10 of 34
The theory that you use to work things out when an object is travelling across the force.
Pythagoras
11 of 34
The name given to equations of motion due to the anagram used of the 5 things involved.
SUVAT
12 of 34
What does S in SUVAT stand for?
Displacement
13 of 34
What does U in SUVAT stand for?
Initial velocity
14 of 34
What does V in SUVAT stand for?
Final velocity
15 of 34
What does A in SUVAT stand for?
Acceleration
16 of 34
What does T in SUVAT stand for?
Time
17 of 34
How many things must you know to find out the rest in SUVAT?
Three
18 of 34
The path of a projectile.
Parabola
19 of 34
An object that is projected or dropped, such as a missile or ball.
Projectile
20 of 34
The angle in degrees at which at which a projectile will travel furthest.
Forty five
21 of 34
What the horizontal and vertical parts of equations of motion are in relation to eachother.
Seperate
22 of 34
The force of attraction between masses.
Gravity
23 of 34
Name the law with which masses have less gravitational force as they become further apart.
Inverse square law
24 of 34
The name of the force that keeps an object moving in a circle that acts towards the centre of the circle
Centripetal force
25 of 34
The path planets take around the sun, caused by the suns gravitational pull giving a centripetal force.
Orbit
26 of 34
Satellites that have an orbit of 24 hours, travel on the equator and stay at the same point above earth.
Geostationary
27 of 34
Satellites that have an orbit of 2 hours, and are 100km above the surface.
Low polar
28 of 34
How big compared to an object another objects reaction force is.
Equal
29 of 34
What a cannon does when a cannonball is fired out of it.
Recoil
30 of 34
The product of mass (kg) and velocity (m/s) in kg m/s.
Momentum
31 of 34
This is what happens to momentum in a collision.
Conserved
32 of 34
The name name of the force that causes things to accelerate towards earth at 10m/s squared.
Gravity
33 of 34
