What is a resulatant force?
The Sum of all Forces
1 of 16
Describe the movement of the car when the resultant force is zero.
Moving at a constant speed
2 of 16
A resultant force of 3600N, acting on a car and its driver, causes the car to accelerate at 3 m/s2. Calculate the mass, in kilograms, of the car and th driver.
1200kg
3 of 16
As an aircraft moves along the runway to take off, its acceleration decreases even though the force from the engines is constant. Explain why
Because the air resistance increases which reduces the resultant force.
4 of 16
How is velocity different from speed?
Velocity has direction
5 of 16
The total momentum of the car was not conserved. What does this statment mean?
What ever momentum it starts with it finishes with.
6 of 16
What is the unit for velocity?
m/s
7 of 16
What is a vector?
A vector has direction as well as magnitude.
8 of 16
What is a scalar?
A scalar is a physical quantity without direction.
9 of 16
Name 3 Vectors.
Weight, Acceleration and Velocity
10 of 16
Name 3 Scalars.
Height, Mass and Distance
11 of 16
What is the force around a pivot called?
A moment.
12 of 16
What is the equation for a moment?
moment of force=force*distance of power
13 of 16
why is the center of mass different for every object?
Because they are all different shapes and sizes.
14 of 16
What is the equation for velocity?
moment/mass
15 of 16
What is the equation for work done?
work done=force*distance
