Understanding Acceleration

Click on the flashcard to see the answer

What is acceleration?

Acceleration is the rate at which an object changes its velocity.

What units are used to measure acceleration?

Acceleration is commonly measured in meters per second squared (m/s²).

How does acceleration relate to velocity?

Acceleration refers to the change in velocity over time.

Can an object be accelerating if it's moving at a constant speed?

Yes, if the direction of the object is changing.

What is the formula for calculating acceleration?

The formula for acceleration is a = (v_f - v_i) / t.

What is uniform acceleration?

Uniform acceleration occurs when an object's acceleration remains constant over time.

Give an example of acceleration in everyday life.

Accelerating on a highway entrance ramp.

How is deceleration related to acceleration?

Deceleration is negative acceleration, meaning the object slows down.

What is the acceleration due to gravity on Earth?

The acceleration due to gravity is approximately 9.8 m/s².

Is acceleration a scalar or a vector quantity?

Acceleration is a vector quantity.

What happens to the acceleration if the net force is doubled?

The acceleration doubles, assuming mass remains constant.

What role does friction play in acceleration?

Friction opposes motion and can decrease acceleration.

How is acceleration depicted on a velocity-time graph?

It is shown as the slope of the line on a velocity-time graph.

What effect does mass have on acceleration?

More mass decreases acceleration when the force is constant.

Can acceleration occur in three dimensions?

Yes, acceleration can occur in three dimensions if the object's velocity changes in any spatial direction.
