Physics S1 Review Part 2

Front

What is the formula to calculate weight?

Back

Weight (F) = mass (m) x acceleration due to gravity (g).

Front

What is the value of acceleration due to gravity on Earth?

Back

Approximately 9.81 m/s².

Front

What is uniform velocity?

Back

Uniform velocity means an object is moving at a constant speed in a straight line.

Front

What is the formula to calculate distance when velocity and time are known?

Back

Distance (d) = velocity (V) x time (t).

Front

What is instantaneous speed?

Back

Instantaneous speed is the speed of an object at a specific moment in time.

Front

What is average speed?

Back

Average speed is the total distance traveled divided by the total time taken.

Front

What is friction?

Back

Friction is a force that opposes the motion of an object, arising from the interaction of surfaces.

Front

What factors affect the amount of friction between two surfaces?

Back

The nature of the surfaces and the normal force pressing them together.

Front

What happens to a falling object when it reaches terminal velocity?

Back

It stops accelerating and continues to fall at a constant speed.

Front

What is the difference between mass and weight?

Back

Mass is the amount of matter in an object, while weight is the force exerted by gravity on that mass.
