What is the best way to describe 'resultant force?'
The average of all the forces on a body
The single theoretical force that equates to all of the actual forces acting on a body
A Jedi thing
What is the resultant force on this truck?
20N
60N
20N to the right
60N to the left
What does Newton's first law say about a body on which a resultant force acts?
It will continue at constant speed
It must be stationary
It will accelerate
From A to B, a car's engine provides a forward force of 200N. The drag force on the car is 100N.
From B to C, the drag force remains the same, but the forward force decreases to 180N.
Which of the following statements is correct?
From A to B the car is accelerating.
From B to C the car is at constant speed.
From A to B the car is accelerating.
From B to C the car is decelerating.
From A to B the car is accelerating.
From B to C the car is still accelerating but at a lower rate of acceleration.
When a skydiver reaches terminal velocity, that means that....
Her acceleration is 9.8 m/s/s
Her weight is equal to her air resistance and her acceleration is zero
Air resistance is high, weight is low
Her weight is zero
Check all the non-contact forces.
Gravity
Air resistance
Friction
Magnetic attraction
Electrostatic repulsion
Work done is....
(2 correct answers)
Similar to energy, measured in Joules
Equal to force x the distance over which the force is acting on a body
Another measure of power
Measured in kW.
On a DISTANCE-TIME chart:
A horizonal line means a stationary object
A straight line diagonally means constant acceleration
A straight line diagonally means an object moving at constant speed
The gradient of a line represents speed
On a VELOCITY-TIME chart:
A horizonal line means an object moving at constant speed
A straight line diagonally means an object moving with constant acceleration
A straight line diagonally means an object moving at constant speed
The gradient of a line represents acceleration
The area under the line represents distance travelled
In terms of speed, acceleration is:
change in speed / distance travelled
mass
change in speed / time taken
average speed / distance travelled
The equation coming from Newton's second law is
F = ma
V = IR
Q = It
a=tv−u
