Category 2 Force and Motion

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 unit of speed?

Back

The unit of speed is kilometers per hour (km/hr).

Front

What does Newton's 3rd Law state?

Back

Newton's 3rd Law states that for every action, there is an equal and opposite reaction.

Front

What is potential energy?

Back

Potential energy is the energy stored in an object due to its position or state. It is greatest at the highest point of an object's motion.

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 force?

Back

Force is a push or pull on an object resulting from the object's interaction with another object. It is measured in newtons (N).

Front

What is mass?

Back

Mass is a measure of the amount of matter in an object, typically measured in kilograms (kg).

Front

What is the formula for calculating acceleration?

Back

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

Front

What is the relationship between mass and weight?

Back

Weight is the force exerted by gravity on an object, calculated as weight = mass × gravity (W = mg).

Front

What is uniform motion?

Back

Uniform motion occurs when an object moves at a constant speed in a straight line.
