Which direction does a friction force act?
Left
Right
Downwards
Always against the motion or pulling force
Which force acts upwards on an object immersed in a fluid?
Flotation force
Water resistance
Anti-gravity
Upthrust
The end of object attracts to both poles of a magnet. What is the object?
Another magnet
A piece of copper
A piece of glass
A piece of iron
If a person pushes a large stationary crate with a force of 250N to the left, but the friction force is 250N to the right...
The forces are balanced and the crate will stay still
The forces add up to 500N so the crate will accelerate
The forces add up to 500N so the crate stands still
The forces are unbalanced so the crate stays still
A cyclist is riding on level ground with a forwards force of 40N. The air-resistance pushing against her is also 40N.
She...
...has a resultant force of 0N so she stops
...has a resultant force of 0N and carries on at the same speed
...has a resultant force of 80N so she accelerates
...has a resultant force of 80N so she decelerates
A car has a forwards driving force of 1200N and air-resistance and friction forces pushing backwards of 500N.
The car will...
Accelerate because the forces are unbalanced and there is a forwards resultant force of 700N
Accelerate because the forces are balanced, with a forwards resultant force of 1700N
Carry on at the same speed
Decelerate
Why are swimmers top speeds lower than runners?
Water is less dense than air and has less resistive force at the same speed.
Water is more dense than air and has more resistive force at the same speed
Water resistance acts upwards
Water resistance is due to particles
When an object falls, it accelerates at first because...
...the air-resistance is greater than its weight
...the air-resistance is equal to its weight
...the air-resistance is smaller than its weight
...the forces on it are balanced
What force keeps planets orbiting the Sun?
Magnetism
Electrostatic
Gravity
The strong nuclear force
Gravity is a force which...
...only attracts very large objects together
...attracts any objects which have an electric charge
...attracts any objects which have mass
...both attracts and repels objects
The Summer season occurs when...
...Earth is closest to the Sun
...The Earth's axis is tilted away from the Sun
...Earth is furthest from the Sun
...the Earth's axis is tilted towards the Sun
Why does Neptune take longer to orbit the Sun than Earth.
Neptune has a larger orbit distance to travel
The force of the Sun's gravity is weaker on Neptune than Earth
Neptune moves more slowly than Earth
All these reasons
What is the angle of tilt of Earth's axis?
10 °
12.5 º
23.5 º
45 º
On what date is the spring equinox when there are 12 hours of daytime and 12 hours of night time?
March 21st
April 21st
February 21st
May 21st
Where in its orbit will Venus appear brightest from Earth?
When it is nearest to Earth
When it is the opposite side to the Sun from Earth
When it is behind the Moon
When the Sun-Venus-Earth angle is 90 º
If your mass is 50 kg, then your weight is approximately...
50N
5N
500N
5000N
