If there is a not-zero resultant force acting on a toy car, what effect will be observed?
An acceleration in the opposite direction of the resultant force.
Nothing.
An acceleration in the direction of the resultant force.
Velocity and Speed are the same thing.
How is a constant deceleration shown on a velocity-time graph?
A positive gradient/slope.
A negative gradient/slope.
A flat line, gradient of 0.
What two forces balance when car travels at a constant speed? (Tick Two)
Resualnt Force
Driving Froce
Weight Force
Braking Force
Friction Force
The two factors that affect a car's overall stopping distance are the reaction time and braking distance.
What is Terminal Velocity?
The highest acceleration.
The speed at which a human dies.
Constant speed reached when upward and downward forces are balanced.
The name given to energy store in a spring is called Elastic Power Energy.
Choose an equation to express the balance when terminal velocity is reached.
R - W = 0
R + W = 0
