RP 2-2 Acceleration and Graphs

Front

What is acceleration?

Back

Acceleration is the rate of change of velocity of an object with respect to time.

Front

What are the units of acceleration?

Back

The units of acceleration are meters per second squared (m/s²).

Front

What does a negative acceleration indicate?

Back

A negative acceleration indicates that the object is slowing down.

Front

How do you calculate acceleration?

Back

Acceleration can be calculated using the formula: a = (final velocity - initial velocity) / time.

Front

What is the acceleration of a car that goes from 0 to 70 m/s in 10 seconds?

Back

The acceleration is 7 m/s².

Front

What does a distance-time graph represent?

Back

A distance-time graph represents the speed of an object.

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 is uniform acceleration?

Back

Uniform acceleration occurs when an object's velocity changes at a constant rate.

Front

What is the formula for calculating distance when acceleration is involved?

Back

The formula is: distance = initial velocity * time + 0.5 * acceleration * time².

Front

What is the significance of the slope in a velocity-time graph?

Back

The slope of a velocity-time graph represents acceleration.
