Newton's 1st & 2nd

Front

What happens to an object in motion when no unbalanced force acts on it?

Back

An object in motion tends to remain in motion in the absence of an unbalanced force.

Front

What is the unit of mass in the International System of Units (SI)?

Back

kg

Front

What is the formula for calculating acceleration?

Back

Acceleration = (Final Velocity - Initial Velocity) / Time

Front

What is Newton's 1st Law of Motion?

Back

An object at rest stays at rest, and an object in motion stays in motion unless acted upon by an unbalanced force.

Front

What is Newton's 2nd Law of Motion?

Back

The acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass (F = ma).

Front

If a truck hits a wall, what happens to the crate in the back of the truck?

Back

The crate continues moving forward until it hits something.

Front

What is the relationship between force, mass, and acceleration?

Back

Force equals mass times acceleration (F = ma).

Front

What is the effect of friction on the motion of an object?

Back

Friction opposes the motion of an object and can cause it to slow down or stop.

Front

How does mass affect the acceleration of an object when a constant force is applied?

Back

Greater mass results in less acceleration when the same force is applied.

Front

What is the definition of acceleration?

Back

Acceleration is the rate of change of velocity of an object.
