Forces and Motion Review

Front

What is acceleration?

Back

Acceleration is the rate of change of velocity of an object. It occurs when an object speeds up, slows down, or changes direction.

Front

What is the formula to calculate force?

Back

Force (F) is calculated using the formula F = mass (m) × acceleration (a).

Front

What is velocity?

Back

Velocity is the speed of an object in a specific direction.

Front

How do speed and velocity differ?

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 unit of force?

Back

The unit of force is the Newton (N).

Front

What is the acceleration of an object if a force of 10 N is applied to a mass of 2 kg?

Back

The acceleration is 5 m/s² (using the formula a = F/m).

Front

What does it mean for an object to be in motion?

Back

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

Front

What is the relationship between mass and acceleration?

Back

According to Newton's second law, the greater the mass of an object, the more force is required to accelerate it.

Front

What is the formula for calculating acceleration?

Back

Acceleration (a) is 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.
