Physics Semester 1 Review

Front

What is the formula to calculate force?

Back

Force (F) = mass (m) × acceleration (a)

Front

What is Newton's second 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.

Front

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

Back

Newton (N)

Front

If a 5 kg object accelerates at 3 m/s², what is the force applied?

Back

15 N

Front

What happens to the forces acting on an object when it speeds up?

Back

The forces are unbalanced.

Front

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

Back

Kilogram (kg)

Front

How do you calculate acceleration?

Back

Acceleration (a) = net force (F) / mass (m)

Front

If a 10 kg object is subjected to a force of 50 N, what is its acceleration?

Back

5 m/s²

Front

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

Back

Mass is the measure of the amount of matter in an object, force is the push or pull on an object, and acceleration is the rate of change of velocity.

Front

What is the effect of balanced forces on an object?

Back

Balanced forces do not change the motion of an object.
