Kinematics Review for GCE 'O' Level Science (Physics)

These flashcards cover key concepts in kinematics, including definitions of speed, acceleration, and their formulas.

What is the formula for calculating speed?

Speed = distance travelled / time taken.

Definition of speed

Spped is that distance that travelled per unit time

What is the SI unit for speed?

The SI unit for speed is metre per second (m/s).

Definiton of speed

speeed is the distance traveled per unit time

What is the difference between average speed and instantaneous speed?

Average speed is constant over the total distance, while instantaneous speed is the speed at a specific moment.

SI unit for instantaneous speed

metre per second (m/s)

Define uniform speed.

Uniform speed is when the distance travelled per unit time is the same.

What is the difference between distance and displacement?

Distance is the total length covered by a moving object, while displacement is the straight-line distance from the starting point with a specified direction.

Velocity definition

velocity is the rate of change in displacement

What is the formula for calculating acceleration?

Acceleration = change of velocity / time taken.

How does uniform acceleration differ from non-uniform acceleration?

Uniform acceleration has a constant rate of change of velocity, while non-uniform acceleration does not have a constant rate.

What does the gradient of a speed-time graph represent?

The gradient of a speed-time graph represents the acceleration of an object.

What is the acceleration due to gravity near the Earth's surface?

The acceleration due to gravity is approximately 10 m/s².

What does the area under a speed-time graph represent?

The area under a speed-time graph represents the distance travelled by the object.
