# Accelerate: friction

TLF ID L1191

Pilot a spaceship in deep space. Find out how friction affects the motion of the spacecraft. Examine velocity-time line graphs showing acceleration as the gradient. This learning object is one in a series of three objects. The series is also packaged as a combined learning object.

#### Educational details

Key learning objectives
• Students distinguish between the concepts of speed and acceleration.
• Students explore relationships between acceleration force and friction.
• Students identify that the greater the friction encountered by a moving object, then the greater the forces need to be applied to achieve a given acceleration.
• Students predict the force needed to overcome friction forces and accelerate at a constant rate.
• Students identify that increasing velocity also increases friction forces.
• Students analyse number patterns in data tables to support Newton's second law of motion.
Educational value
• Introduces SI units for velocity, acceleration, force and mass.
• Introduces velocity versus time line graphs; explains that the slope of the line indicates acceleration.
• Encourages students to interpret velocity versus time line graphs.
• Enables students to generate and interpret data that support Newton’s second law of motion.
