What is the formula for speed?
Speed = Distance x Time
Speed = Time / Distance
Speed = Distance + Time
Speed = Distance / Time
Define acceleration.
Acceleration is the rate of change of velocity with respect to time.
Acceleration is the distance traveled divided by the time taken.
Acceleration is the force acting on an object.
Acceleration is the speed of an object.
How is acceleration calculated?
acceleration = final velocity / time
acceleration = (final velocity * initial velocity) / time
acceleration = (final velocity + initial velocity) / time
acceleration = (final velocity - initial velocity) / time
Explain the concept of distance-time graphs.
Distance-time graphs are used to measure weight and distance
Distance-time graphs illustrate the relationship between distance and time for an object's motion.
Distance-time graphs show the relationship between speed and time
Distance-time graphs are only applicable to stationary objects
What does a horizontal line on a distance-time graph represent?
Object decelerating
Object in motion
Object at rest
Object accelerating
Describe the slope of a distance-time graph.
The slope of a distance-time graph represents the color of the object.
The slope of a distance-time graph represents the speed or velocity of an object.
The slope of a distance-time graph represents the temperature of the object.
The slope of a distance-time graph represents the weight of the object.
What information does a velocity-time graph provide?
It displays the weight of an object
It indicates the temperature of the environment
It reveals the color of the object
It shows the acceleration, deceleration, constant velocity, and direction of motion of an object.
How is velocity calculated from a velocity-time graph?
Velocity is calculated by finding the maximum value on the velocity-time graph.
Velocity is calculated by finding the area under the velocity-time graph.
Velocity is calculated by finding the y-intercept of the velocity-time graph.
Velocity is calculated by finding the slope of the velocity-time graph.
What does a horizontal line on a velocity-time graph indicate?
Acceleration
Decreasing velocity
Increasing velocity
Constant velocity
Differentiate between speed and velocity.
Speed and velocity are the same thing.
Speed is scalar, velocity is vector.
Speed is a vector, velocity is scalar.
Speed is a measure of distance, velocity is a measure of time.
How does acceleration affect an object's motion?
Acceleration always causes an object to slow down
Acceleration changes the velocity of an object over time.
Acceleration only affects the color of an object
Acceleration has no effect on an object's motion
What is the relationship between distance and time in a speed-time graph?
The relationship between distance and time in a speed-time graph is exponential
Distance and time in a speed-time graph have no correlation
The relationship between distance and time in a speed-time graph is a direct proportion
The relationship between distance and time in a speed-time graph is represented by the slope of the line.
How can you determine the acceleration of an object from a velocity-time graph?
Find the slope of the velocity-time graph.
Calculate the area under the velocity-time graph.
Divide the time by the change in velocity.
Use the y-intercept of the graph.
What does a curve on a velocity-time graph signify?
Negative velocity
Changing acceleration
Time travel
Constant speed
Explain the significance of the area under a velocity-time graph.
The area under a velocity-time graph represents the speed of an object
The area under a velocity-time graph indicates the acceleration of an object
The area under a velocity-time graph shows the time taken for an object to reach a certain velocity
The significance of the area under a velocity-time graph is that it gives the displacement of an object.
One of the following is not a vector quantity. This one is :
displacement
speed
acceleration
velocity
If a particle moves with a constant speed, the distance-time graph is a
stair like line
circle
straight line
polygon
In a free fall the velocity of a stone is increasing equally in equal intervals of time under the effect of gravitational force of the earth. Then what can you say about the motion of this stone? Whether the stone is having:
Uniform acceleration
Non-uniform acceleration
Retardation
Constant speed
When a car driver travelling at a speed of 10 m/s applies brakes and brings the car to rest in 20 s, then the retardation will be:
+ 2 m/s2
− 2 m/s2
− 0.5 m/s2
+ 0.5 m/s2
The average velocity of a body is given by the expression :
v = u+ at
2as = v2− u2
Vav=(u + v)/2
S= ut + ½ a t2
