Unit 2 - Motion Review

Front

What is motion?

Back

Motion is the change in position of an object over time.

Front

What is the formula for calculating distance in free fall?

Back

Δx = 1/2 g t², where g is the acceleration due to gravity (approximately 9.81 m/s²) and t is the time in seconds.

Front

What does constant velocity mean?

Back

Constant velocity means an object is moving at a steady speed in a straight line without changing direction.

Front

What is acceleration?

Back

Acceleration is the rate of change of velocity of an object. It can be positive (speeding up) or negative (slowing down).

Front

What is the difference between speed and velocity?

Back

Speed is a scalar quantity that refers to how fast an object is moving, while velocity is a vector quantity that includes both speed and direction.

Front

What does a flat line on a distance-time graph represent?

Back

A flat line indicates that the object is stationary and not changing its position.

Front

What is the significance of the slope on a distance-time graph?

Back

The slope of a distance-time graph represents the speed of the object; a steeper slope indicates a higher speed.

Front

What is free fall?

Back

Free fall is the motion of an object under the influence of gravity only, with no air resistance.

Front

What is the acceleration due to gravity?

Back

The acceleration due to gravity on Earth is approximately 9.81 m/s².

Front

How do you calculate the distance fallen by an object in free fall after a certain time?

Back

Use the formula Δx = 1/2 g t².
