ACP Homework 1

Front

What is acceleration?

Back

Acceleration is the rate of change of velocity of an object. It is measured in meters per second squared (m/s²).

Front

What is the formula for calculating force?

Back

Force (F) is calculated using the formula F = m × a, where m is mass in kilograms and a is acceleration in meters per second squared.

Front

What is the unit of force?

Back

The unit of force is the Newton (N).

Front

If a bowling ball has a mass of 25 kg and is accelerated at 2 m/s², what is the force applied?

Back

F = m × a = 25 kg × 2 m/s² = 50 N.

Front

What does it mean if an object is in motion?

Back

An object is in motion if it changes its position over time relative to a reference point.

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 the acceleration of an object moving at a constant speed?

Back

The acceleration of an object moving at a constant speed is 0 m/s².

Front

What is the gravitational acceleration on Earth?

Back

The gravitational acceleration on Earth is approximately 9.8 m/s².

Front

How do you calculate the acceleration of an object?

Back

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

Front

What is inertia?

Back

Inertia is the tendency of an object to resist changes in its state of motion.
