What is speed?

Back

Speed is the distance traveled per unit of time, typically measured in meters per second (m/s) or miles per hour (mph).

What is velocity?

Back

Velocity is the speed of an object in a specific direction, expressed in units such as meters per second (m/s).

Front

What does a velocity-time graph represent?

Back

A velocity-time graph shows how the velocity of an object changes over time, with time on the x-axis and velocity on the y-axis.

Front

What does it mean when an object is speeding up?

Back

An object is speeding up when its velocity is increasing over time, which is represented by a positive slope on a velocity-time graph.

Front

What does it mean when an object is slowing down?

Back

An object is slowing down when its velocity is decreasing over time, which is represented by a negative slope on a velocity-time graph.

Front

What is net force?

Back

Net force is the total force acting on an object, taking into account both the magnitude and direction of all individual forces.

Front

How do you calculate distance using speed and time?

Back

Distance = Speed × Time. For example, if a car travels at 50 mph for 2 hours, the distance covered is 50 mph × 2 hours = 100 miles.

Front

What is the formula for calculating force?

Back

Force = Mass × Acceleration (F = m × a).

Front

What is inertia?

Back

Inertia is the tendency of an object to resist changes in its state of motion, meaning it will stay at rest or continue moving at a constant velocity unless acted upon by a net force.

What is the difference between mass and weight?

Back

Mass is the amount of matter in an object, measured in kilograms (kg), while weight is the force exerted by gravity on that mass, measured in newtons (N).
