Forces and Motion Review

Front

What is acceleration?

Back

Acceleration is the rate at which an object's velocity changes over time. It is measured in meters per second squared (m/s²).

Front

How do you calculate acceleration?

Back

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

Front

What is the formula for weight?

Back

Weight (W) is calculated using the formula: W = mass (m) × gravitational acceleration (g).

Front

What is the unit of force?

Back

The unit of force is the Newton (N).

Front

What happens when two forces of equal magnitude act in opposite directions?

Back

When two forces of equal magnitude act in opposite directions, they cancel each other out, resulting in no movement.

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

If a boat reduces its velocity from 9.5 m/s to 5.5 m/s over a distance of 12.0 m, what is its acceleration?

Back

The acceleration is 2.5 m/s².

Front

What is the effect of a constant force on an object?

Back

A constant force will cause an object to accelerate in the direction of the force.

Front

What is the relationship between mass and weight?

Back

Weight is the force exerted by gravity on an object, which is directly proportional to its mass.

Front

What is the formula for calculating distance when acceleration is constant?

Back

Distance (d) can be calculated using the formula: d = initial velocity (u) × time (t) + 0.5 × acceleration (a) × time².
