Physics: Speed, Velocity, and Acceleration

Front

Speed and velocity are both how fast you're going.

Back

Speed is how fast you're going without regard to direction. Velocity includes direction.

Front

Acceleration formula.

Back

Front

Area under a velocity-time graph

Back

Equal to the distance traveled in that time interval.

Front

Velocity-time graph with a positive gradient

Back

Indicates acceleration.

Front

Velocity-time graph with a negative gradient

Back

Indicates deceleration.

Front

Weight and mass are not the same.

Back

Mass is the amount of 'stuff' in an object, while weight is a force due to acceleration due to gravity.

Front

Weight calculation example.

Back

For a 5 kg mass: - On Earth: W = 5 \times 10 = 50 N - On the Moon: W = 5 \times 1.6 = 8 N

Front

Weight formula application.

Back

Use W = m \times g to calculate weight in newtons.

Front

Weight's dependency on gravity.

Back

Weight changes with the strength of the gravitational field.

Front

Mass measurement consistency.

Back

Mass remains the same regardless of location.
